Progeny: offspring, children.
Recessive: the allele that can be masked by an alternative allele in the heterozygote state, such that the phenotype of a recessive allele may only be identified in the homozygote state.
The subsequent generation following a mating or crossing of parents; offspring.
Also called adaptive value. The relative reproductive success of a genotype as measured by survival, fecundity or other life history parameters. See Darwinian fitness and natural selection.
The subsequent generation following a mating or crossing of parents; offspring.
Genetic drift observed in a population founded by a small non representative sample of a larger population.
The progeny of these cells move into the basal layer of the epidermis and the matrix of the hair follicle where they continue to divide, differentiate and eventually die.
All F1 progeny produced in these crosses were monohybrids, heterozygous for one character.
A cross between two heterozygotes is a monohybrid cross.
All the ~ would be spherical-seeded and tall.
1/2 would be spherical-seeded and intermediate height; 1/2 would be spherical-seeded and tall.
The number of ~ counted in a well that resulted from each query-target pair and control combination was counted and recorded as growth scores. A well with no ~ was given a growth score of zero, whereas a well overgrown with ~ was given a growth score of six.
F2 hybrid. ~ of F1 b x s matings. Genetically dissimilar.
F3, etc. Subsequent b x s hybrid matings.
Feral. Wild populations of commensal species (mice) that have become independent of human habitats or human food.
Since one copy of each chromosome remains normal, both parent and ~ with such a translocation are heterozygous , or "balanced" carriers. Half their gametes will include one copy of each gene, either on the translocated chromosomes or their normal homologs.
(D) The number of ~
In a haplodiploid population, r is:
(A) Greater for the mother/daughter relationship than for the father/daughter relationship ...

So a very small number of stem cells can give rise to an enormous number of mature ~. Now, there are several different kinds of stem cells. There are somatic stem cells. These are the ones that live in the adult organism.
The initial phases of tumor expansion can be represented as a rooted binary tree  where daughter cells inherit all mutations of the parent, acquire new ones, and pass old and new mutations to the ~ (Figure 1A).
Recombination The process by which ~ derive a combination of genes different from that of either parent. In higher organisms, this can occur by crossing over.
Regulatory regions or sequences A DNA base sequence that controls gene expression.
0505 in the next generation because of the chance production of a few more or less ~ of each genotype. In the second generation, there is another sampling error based on the new gene frequency, so the frequency of "a" may go from 0.0505 to 0.501 or back to 0.498.
The mixture of sperm and egg resulted in ~ that were a "blend" of two parents' characteristics. Sex cells are known collectively as gametes (gamos, Greek, meaning marriage).
He deduced the laws of inheritance purely from observations of the ~ of his pea plants. The discovery that DNA is the genetic material occurred in the first half of the 20th century.
chromosomes are passed down from one generation to the next they begin to diverge, not because they're mixing up their genes but because of accumulating mutations, so that as time goes on, you might have mitochondrial chromosome of a particular type which is then left to many, many ~ in the ...
That which is generated or brought forth; ~; offspiring.
4. A single step or stage in the succession of natural descent; a rank or remove in genealogy.
R selections organisms are those that maximize the number of ~, the number of off springs they have on giving very little resources to each individual off spring.
(1) The non-parental arrangement of alleles in ~ that can result from either independent assortment or crossing over.
(2) In general, any process in a diploid or partially diploid cell that generates new gene or chromosomal combinations not found in that cell or in its progenitors.
The number of recombinants divided by the total number of ~. The recombination frequency is proportional to the physical distance between two genetic markers, and thus recombination frequencies can be used to draw genetic maps showing the relat ive distance between genetic markers.
Coli with 35S T2, and collected the ~. The results found that the ~ collected from the 32P E.Coli and 32P T2 contained the 32P isotope, while the 35S strains did not, providing more evidence that DNA was the genetic information that bacteriophages inject into bacteria, not protein.
reproductive success The number of ~ born, or surviving ~ produced by an organism.
reptiles Vertebrates with scales on their skin and leathery eggs that are laid on land. Marine reptiles include sea turtles, sea snakes, the marine iguana, and the saltwater crocodile.
daughter plants. Vegetative ~ of strawberry plants; plants that develop along the runners produced by another strawberry plant called the mother plant.
day-neutral. The term applied to strawberry cultivars that produce flower buds more or less independently of day length; everbearing.
One exception: culturing human epithelial stem cells and using their differentiated ~ to replace a damaged cornea. This works best when the stem cells are from the patient (e.g. from the other eye).
an inheritance pattern in which all the ~ have the genotype and phenotype of the maternal parent

recombination The occurrence of ~ having combinations of traits different from the combinations seen in the parents (due to crossing-over and independent segregation of chromosomes).
Some individuals may thrive under a particular environmental factor, while other individuals may fail to thrive. Individuals that fail to thrive may leave fewer ~, while those that thrive may leave a larger number of ~.
The ~ of the cross are selfed over several generations in so that they are homozygous at all loci, but each RI has a distinct recombinant geneotype. In these lines, genetic distance is calculated based upon the recombination frequencies between molecular markers (e.g. CAPS, SSLP markers).
Mutation An allele present in a ~ that is not present in the genome of either its parents.
See Mutation in the MGI Glossary.
Antibody produced by the ~ of a single B cell and thus a homogeneous protein exhibiting a single antigen specificity. Experimentally, it is produced by use of a hybridoma. (Figure 6-10)
Recombination: The process by which ~ derive a combination of genes different from that of either parent.
(i) which is the recessive trait. (ii) express the gene type of parents F1 & F2 ~?
Mendel crossed a pure white pea plant with pure red flowered plant. In F1 generation all flowers were red. (i) which is the recessive trait. (ii) express … ...
So that those changes in the organism be considered in the context of the evolutionary adaptation, they should occur in the DNA. In this way, the change will be inherited to the ~.
Hfr: A male bacterial cell that has the F factor integrated into its chromosome is an Hfr (high frequency of recombination) cell. Crosses between Hfr cells and F- females produce far more recombinant ~ than do crosses between F+ males and F- females.
The resulting mouse will be chimaeric but, if you are lucky (and if you've gotten this far, you obviously are), its germ cells will carry the deleted gene. A few rounds of careful breeding can then produce ~ in which both copies of the gene are inactivated.
to another via bacteriophage) and bacterial conjugation (the transfer of DNA from one bacterial cell to another via a special protein structure called a conjugation pilus). Bacteria, having acquired DNA from any of these events, can then undergo fission and pass the recombined genome to new ~ ...
