Analyze the first question

The first question asks for the probability of a child being homozygous recessive when both parents are heterozygous.

Using the Punnett Square concept, we represent the heterozygous parents with alleles \(Aa\) and \(Aa\). Crossing these parents yields:

• \(AA\) (homozygous dominant): 1 out of 4 (\(25\%\))
• \(Aa\) (heterozygous): 2 out of 4 (\(50\%\))
• \(aa\) (homozygous recessive): 1 out of 4 (\(25\%\))

Thus, the probability of a homozygous recessive child is \(25\%\).

Analyze the second question

The second question asks when paired alleles separate and go to different gametes.

Using the Meiosis concept, homologous chromosomes (and thus paired alleles) segregate during the formation of gametes. This physical separation of alleles is the biological basis of Mendel's Law of Segregation, which occurs specifically during the cell division process of meiosis.
