in garden peas, yellow seeds (y) are dominant to green seeds (y), and inflated pods (i) are dominant to constricted pods (i). suppose you have crossed yyii parents with yyii parents. draw the f1 punnett square and predict the expected f1 phenotype(s). list the genotype(s) of gametes produced by f1 individuals. draw the f2 punnett square. based on this punnett square, predict the expected phenotype(s) in the f2 generation and the expected frequency of each phenotype.

Complete question:

In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i).

Suppose you have crossed YYII parents with yyii parents.

Draw the F1 Punnett square and predict the expected F1 phenotype(s). List the genotype(s) of gametes produced by F1 individuals. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.  F1 phenotype ⇒ 100% plants heterozygous for both traits, expressing yellow seeds and inflated pods, YyIi. F1 gametes ⇒ YI, Yi, yI, yiF2 Phenotype ⇒ 9/16 are expected to be plants with yellow seeds and inflated pods,    Y-I-3/16 are expected to be plants with yellow seeds and constricted pods, Y-ii3/16 are expected to be plants with green seeds and inflated pods, yyI-1/16 are expected to be plants with green seeds and constricted pods, yyii

Explanation:

Available data:

yellow seeds (Y) are dominant to green seeds (y)   inflated pods (I) are dominant to constricted pods (i)
