In squash plants, the allele for yellow fruit (y) is dominant to the allele for green fruit (y). a plant with genotype yy is crossed with a plant with genotype yy.

what are the expected genotype percentages in the offspring of this cross?

question options:

a)

100% heterozygous and 0% homozygous

b)

50% homozygous dominant and 50% heterozygous

c)

50% homozygous dominant and 50% homozygous recessive

d)

25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive

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?

Diffusion and osmosis are forms of passive transport
