17. What are all the possible gamete combination if a parent is heterozygous for both traits (AaBb)? (Select all that apply) aB BB greener aa Aa Bb Ab ab bb

## Step 1<br />The problem involves understanding the principles of genetics, specifically the concept of gamete formation in a parent with heterozygous traits. The parent in question is heterozygous for both traits, which is represented as (AaBb).<br /><br />## Step 2<br />The parent can produce four types of gametes due to the law of independent assortment. This law states that allele pairs separate independently during the formation of gametes. <br /><br />## Step 3<br />The four possible gamete combinations are: AB, Ab, aB, and ab. These combinations are formed by randomly selecting one allele from each gene.<br /><br />## Step 4<br />The options BB, aa, and bb are not valid gamete combinations because they do not represent a combination of alleles from both genes.<br /><br />## Step 5<br />The options greener and Aa are not valid gamete combinations because they do not represent a combination of alleles from both genes.
