Consider a diploid organism. What is the genotypic ratio expected to be observed in the offspring produced by two heterozygous parents

See the answer below

Explanation:

A diploid organism is one that has 2 copies of each of its genes. When the two genes are the same, they are said to be homzygous, and when they are different, they are said to be heterozygous.

In this case, let us assume that the trait in question is represented by A for the dominant version and a for the recessive version. Since the parents are heterozygous, it means their genotypes would be Aa.

      Aa    x    Aa

   AA   Aa   Aa   aa

Hence, the genotype ratio would be 1AA:2Aa:1aa. In other words, the genotypic ratio of homzygous to heterozygous offspring would be 1:1 because AA and aa are both homzygous while Aa is heterozygous.

the answers are a and c
