Question

1. the diagram shows a diploid cell with two homologous pairs of chromosomes. due to independent assortment, the possible allele combinations that could be found in gametes produced by meiosis are -

Explanation:

Step1: Understand independent assortment

Independent assortment states that alleles of different genes assort independently during gamete formation.

Step2: Analyze the alleles

We have two pairs of alleles: \(B/b\) and \(D/d\).
For the \(B/b\) pair, the possible alleles in gametes are \(B\) or \(b\). For the \(D/d\) pair, the possible alleles in gametes are \(D\) or \(d\).

Step3: Combine the alleles

Using the principle of independent assortment, we combine the alleles from each pair.

• When \(B\) combines with \(d\), we get \(Bd\).
• When \(B\) combines with \(D\), we get \(BD\).
• When \(b\) combines with \(d\), we get \(bd\).
• When \(b\) combines with \(D\), we get \(bD\).

Answer:

B. Bd, BD, bD, and bd
