Definition of hypothesis :
An assumption not proved by experiment or observation that is made for the sake of testing its soundness.
The Lyon hypothesis states that in cells with multiple X chromosomes, all but one is inactivated during mammalian embryogenesis. X-inactivation leads to clumped chromatin termed Barr bodies, which are generally considered inert.
A hypothesis to explain quantitative variation by assuming the interaction of a large number of genes (polygenes) each with a small additive effect on the character.

Makehams hypothesis
a development of gompertz hypothesis as to the force of mortality following some mathematical law. Makeham assumed that death was the consequence of two generally coexisting causes: 1) chance; 2) a deterioration or increased ...

Hypothesis
A hypothesis is a scientist's best guess about what might happen in an experiment.

hypothesis -- A concept or idea that can be falsified by various scientific methods.
ingroup -- In a cladistic analysis, the set of taxa which are hypothesized to be more closely related to each other than any are to the outgroup.

Hypothesis
A hypothesis is an explanation of an observation. Kettlewell explained his observation by saying that birds preyed more on the dark form when the trees were light colored and they preyed more on the light form when the trees were dark.
hypothesis, which is sometimes called the "replacement hypothesis," postulates that modern Homo sapiens spread out of Africa, into Europe and Asia, and replaced archaic Homo sapiens living in those regions (Fig. 5).
hypothesis A tentative explanation of a question; an explanation based on careful observations.
hypothesis A statement or proposition that can be tested by experiment.
The hypothesis that the experimental treatment had no effect is called the null hypothesis.
Which hypothesis is correct? Scientists can often use the same "evidence" to support contrasting hypotheses depending on which evidence (fossils or molecular clock/DNA studies) one gives more weight to.
Sequence hypothesis. Francis Crick's seminal concept that genetic information exists as a linear DNA code; DNA and protein sequence are colinear.
A hypothesis proposed by Francis Crick to explain how one tRNA may recognize two different codons that differ in the third position. The three bases in the anticodon of each tRNA are antiparallel to the three bases of the codon in the mRNA.
on the X chromosome, of having the same level of the products of those genes as males (who have a single X chromosome). This is due to the process of random inactivation of one of the X chromosomes in females (Lyonization). See Lyon's hypothesis.
Chemiosmotic hypothesis The idea that electron transfer in the respiratory chain is used to pump protons across the inner mitochondrial membrane, establishing a proton gradient; ...
A recently offered hypothesis suggests that phylogenetic species concepts and the biological species concept may be highly, if not completely, incompatible.
In 1996 its completed sequencing and analysis confirmed that the "tree of life" has three domains, a hypothesis first advanced nearly 20 years ago by Carl Woese (University of Illinois) but not given much credence at the time. The single-celled M.
As suggested by this hypothesis, the two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one.
Gregor Mendel developed a hypothesis about how genes are passed from parents to their offspring. This hypothesis, which scientists still use today, says that a pea plant (And all other life forms) have two genes, for tallness, making a gene pair.

Null hypothesis states that there are no significant differences between sets of data
