Multiple Choice

Based on the gene diagram shown below, which of the following best explains Mendel's Law of Segregation?

Alleles for different genes always assort together during gamete formation.

Genes are blended together in the offspring, resulting in intermediate traits.

Dominant alleles are always inherited together with recessive alleles.

Each individual has two alleles for each gene, and these alleles separate during gamete formation so that each gamete receives only one allele.

Verified step by step guidance

Understand that Mendel's Law of Segregation states that an individual carries two alleles for each gene, one inherited from each parent.

Recognize that during gamete formation (meiosis), these two alleles separate so that each gamete receives only one allele.

Note that this separation ensures that offspring inherit one allele from each parent, maintaining genetic variation.

Distinguish this law from other concepts such as independent assortment (which involves different genes) and blending inheritance (which is an outdated concept).

Apply this understanding to interpret gene diagrams by identifying how alleles segregate into different gametes, confirming that alleles do not blend or always stay together.
