Hybridization
The process of joining two complementary strands of DNA or one each of DNA and RNA to form a double-stranded molecule.
- An offspring or cross between two genetically unlike individuals
Hybridization
- Production of offspring, or hybrids, from genetically dissimilar parents. In selective breeding, it usually refers to the offspring of two different species.
The F1 offspring showed only one of the two parental traits, and always the same trait.
Results were always the same regardless of which parent donated the pollen (was male).
If the offspring of selected parents occupy the same range as the entire population, environmental factors are working alone. The trait has a zero heritability.
hybrid Offspring of a cross between two species or between alternate homozygous conditions.
hybridoma Fused product of a normal and a myeloma (cancer) cell, which has some of the characteristics of the normal cell.
Problem 10: Offspring of human females who are carriers for X-linked traits
A human female "carrier" who is heterozygous for the recessive, sex-linked trait red color blindness, marries a normal male.
Hybrid. The offspring of two parents differing in at least one genetic characteristic (trait). Also, a heteroduplex DNA or DNA-RNA molecule.
Parents pass on a particular copy of a gene to their offspring. As stated supra note 1, each parent donates a haploid number of chromosomes to the offspring, giving it a diploid number.
"If a population is finite in size (as all populations are) and if a given pair of parents have only a small number of offspring, then even in the absence of all selective forces, ...
In sexual populations half the individuals are male and cannot themselves produce offspring. This means that an asexual lineage will have roughly double the rate of population growth under ideal conditions.
When one parent carries a mutation in one copy of the RB tumor suppressor gene, it is transmitted to offspring with a fifty percent probability.
Again he crossed pure breeding parents and then their offspring (F1) were allowed to self pollinate. He consistently saw a ratio of 9:3:3:1 in the resulting F2 generation and reasoned backwards to say that each trait assorted independently.
When two individuals that are carriers meet and produce an offspring, if that offspring inherits the changed or misspelled copy of the gene from each parent, that individual, that offspring, ...
What will the offspring's gene pair look like? This is a bit more tricky isn't it. Some of the plants will inherit a (T) from the mother plant, and a (T) from the father plant.
Moving up the scale towards more than one organism, genetics considers how heredity works between parent and offspring. Ethology considers group behavior of more than one individual.
A group of organisms belong to the same biological species, if they are capable of interbreeding to produce fertile offspring.
Genetic recombinant is an offspring having a non-parental allele combination. For example, crossing between parental Aa Bb and aa bb can have offsprings with the following non-parental genotypes: Aa bb or aa Bb.
Fitness A measure of an organism's or a genotype's ability to leave offspring in the next generation.
Seeds let you send your offspring out into the world. Seeds provide a protective coat so that the embryo plant can develop when it finds a nice piece of soil. But remember this: gymnosperms have not developed the ability to make flowers.
Males (if heterogametic) contribute either an X or Y to the offspring, while females contribute either X. The male thus determines the sex of the offspring. Remember that in meiosis, each chromosome is replicated and one copy sent to each gamete.
The functional and physical units of heredity passed from parent to offspring, genes are pieces of DNA stored in the cell nucleus. They are the recipes for making proteins. Each gene consists of several thousand code words.
reproduction -- The manufacture of offspring as part of an organism's life cycle. This is not the same as dispersal. Reproduction may be sexual, involving the fusion of gametes, or asexual.
reticulate -- Interconnecting, like a network.
In a given population of organisms, there are heritable traits that enable some members to contribute a larger number of offspring than others.
In genetic mapping studies an offspring having a non-parental allele combination. An individual or cell with a genotype produced by recombination.
Also known as: non-parental
Was this definition helpful?
the total number of offspring who themselves survive to reproduce). It can be seen as the extent to which an individual successfully passes on its genes to the next generation.
Backcross
A genetic cross between an offspring and one of its parents or an organism genetically identical to one of its parents.
Bacteriophage (or simply Phage)
A virus that infects a bacterium.
Fitness: The ability to survive to reproductive age and produce viable offspring. Fitness also describes the frequency distribution of reproductive success for a population of sexually mature adults.
neoteny - method of reproduction in which the offspring is produced while an organism is still in, or maintains many characteristics of, its larval or juvenile stage. Phylloxerans (Homoptera) exhibit neoteny, as do salamanders.
asexual reproduction
A type of reproduction involving only one parent that produces genetically identical offspring by budding or by the division of a single cell or the entire organism into two or more parts.
oviparous - producing offspring from externally laid eggs. Contrast with viviparous ...
Species: A group of individuals similar in structure and capable of interbreeding and producing fertile offspring. They are different in structure from other such groups and do not interbreed with them.
Natural selection the differential reproductive success of individuals within a population‚ the ability of individuals to survive and leave the most reproducing offspring
(nata = born‚ produced) ...
inherited from each parent, physically swap sections with one another. This creates hybrid chromosomes that are a patchwork of the original pair. Crossing over occurs in species that reproduce sexually and increases the genetic variety of offspring.
Transgenic organism -- one into which a cloned genetic material has been experimentally transferred, a subset of these foreign gene express themselves in their offspring.
