predicting genotype and phenotype frequencies of progeny Pre

Predicting genotypes and phenotypic frequencies of progeny if the cross in Part B. predict the frequencies of each of the phenotypes in the F_1 progeny, and determine the genotype(s) present in each phenotypic d the diagram by dragging the correct label to the appropriate location. Labels can be used once, more than once, or not at all.

Solution

Answer:

RrYy x rrYy

Round genotypes= RrYy, RrYY

Wrinkled genotypes= rrYy, rrYY

Yellow genotypes = YY, Yy

Green genotypes = yy

Probability of RrYy and RrYY = ½ x ¼ = 1/8

Probability of rrYy and rrYY=½ x

Probability of YY, Yy= ¼+½ =¾

Probability of yy=¼

Expected frequencies =

Round = ½

Wrinkled=½

Yellow= ¼+½ =¾

green=¼

Progeny genotypes:

Rr YY, RrYy

rrYy, rrYY

YY, Yy

rryy
