How would you explain to a classmate the process of using a Punnett square for a cross between one pea plant with genotype Tt and a second pea plant with genotype Tt, where T is the allele for a tall pea plant, and t is the allele for a short pea plant? Make sure to describe how you would find the probability that a given offspring of the two parents is tall or short.

Compare and contrast region e in the illustration above with region d. describe the physical characteristics of each region.

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?
