Chicken embryos express both hoxc6 and hoxc8 in regions where ribs form, but only hoxc6 in regions where forelimbs form. the fossilized jawbone of a new species of animal was found, and enough dna was extracted to discover that it had both hoxc8 and hoxc6 genes. which of the following is true of this new species?
a) it definitely has forelimbs.
b) it definitely does not have forelimbs.
c) can't tell without knowing the gene expression pattern.
d) can't tell because chicken genes tell us nothing about other species.

Which is an example of a population?

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?
