Answer 1

Answer: All of this means there can be three "types" of genotypes:

This is only when BOTH alleles are dominant, represented as "AA".

This is only when the alleles are different, represented as "Aa".

This is only when the alleles are recessive, represented as "aa".

Examples:

1- If both parents have a heterozygous genotype (Aa), their offspring could inherit either an A or an a allele from each parent. This would result in a Punnett square with a 25% chance of AA, a 50% chance of Aa, and a 25% chance of aa genotypes.

2- If one parent has a homozygous dominant genotype (AA) and the other parent has a homozygous recessive genotype (aa), all of their offspring would have a heterozygous genotype (Aa).

RULE: When you are writing a genotype, always write the dominant allele first, followed by the recessive allele (e.g., Aa, not aA).
