Question
a cross is performed between plant with genotype TtYy and a plant with genotype TtYy. If the two genes independently assort, what is the probability expressed as a decimal that the offspring will be homozygous for gene T and homozygous for gene Y a cross is performed between plant with genotype TtYy and a plant with genotype TtYy.

If the two genes independently assort, what is the probability expressed as a decimal that the offspring will be homozygous for gene T and homozygous for gene YExplanation / Answer
TtYy *TtYy male
The offspring will be homozygous for gene T and homozygous for gene Y means it should be TTYY
The probability that offspring will be homozygous for gene T (TT) = 4/16 = 1/4
The probability that offspring will be homozygous for gene Y (YY) = 4/16 = 1/4
The probability that the offspring will be homozygous for gene T and homozygous for gene Y = 1/4*1/4 = 1/16 = 0.0625 (ans)
or simply from punnet square we can say that the probabiloty of TTYY = 1/16 = 0.0625 (ans)
