Ascientist argues that two species of birds are the same species because they have similar body structure, similar dna, and similar beaks because they eat the same food. the birds do have some variations in color patterns and have a different mating season. which piece of evidence would go against this argument and suggest that the birds are actually different species? the birds have similar body structure. the birds have similar beaks. the birds have different color variations. the birds have different mating seasons.

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?

Explain how the number of similarities between the embryos from early stage to late stage is used as evidence of a common ancestry

Why has two different alleles for the same trait?
