c) Note the following dihybrid cross: Parent 1 is crossed with Parent 2 a pea plant that is heterozygous for pod color and has a rough seed coat a pea plant that has a yellow pod color and is Heterozygous for seed coat Carefully write out the Genotypes of both Parent 1 and 2. Then write out the possible different gametes each parent can make. (Remember the "mantra." How many genes of each trait can be in one gamete?) Then make a Punnett square. (Remember that a Punnett square only needs to be as big as the number of different gametes and this problem does not need a 4x4 Punnett square.) Now for the f1 generation, give the possible genotypes and their ratios and the phenotypes and their ratios.

Question

Assume green pea pods are dominant over yellow pea pods, and assume  smooth seed coats are dominant over rough seed coats.

c) Note the following dihybrid cross:
Parent 1
is crossed with
Parent 2
a pea plant that is
heterozygous for pod color and
has a rough seed coat
a pea plant that has a
yellow pod color and
is Heterozygous for seed coat
Carefully write out the Genotypes of both Parent 1 and 2. Then write out the possible different
gametes each parent can make. (Remember the "mantra." How many genes of each trait can
be in one gamete?) Then make a Punnett square. (Remember that a Punnett square only needs
to be as big as the number of different gametes and this problem does not need a 4x4 Punnett
square.) Now for the f1 generation, give the possible genotypes and their ratios and the
phenotypes and their ratios.
