Question

A heterozygous y'all yellow plant is crossed with a homozygous short green. What will be the genotypes and phenotypes, and probabilities of the first generation?

Answer 1

genotypes Tt Yy , Ttyy

phenotypes tall and yellow , tall and green

probanility 1/2 , 1/2

Step-by-step explanation:

symbols T= tall,t= short, Y = yellow, y = short

parental phenotype tall heterozygous yellow x short homozygous green

parental genotype TTYy ttyy

meiosis

gametes TY Ty ty

random fertilisation

offspring genotype TtYy and Ttyy

offspring phenotype tall and yellow tall and green

probability 1/2 1/2
