Vedclass · Answer

(D) The cross between a heterozygous individual $(Aa)$ and a homozygous recessive individual $(aa)$ is known as a test cross.According to Mendelian genetics,the Punnett square for this cross $(Aa 	imes aa)$ results in gametes $A$ and $a$ from the male,and $a$ from the female.This produces offspring with genotypes $Aa$ and $aa$ in a $1:1$ ratio.For $1000$ total offspring,the expected distribution is $500\ Aa$ and $500\ aa$.Option $(d)$ $481\ Aa : 519\ aa$ represents the closest observed experimental result to the theoretical $1:1$ ratio.

If enough crosses are made between male flies of the genotype $Aa$ and female flies of the genotype $aa$ to produce about $1000$ offspring,which one of the following is the most likely distribution of genotypes in the offspring?
