Multiple Choice

Which statement best describes the principle of independent assortment in genetics?

Only dominant alleles are passed on to offspring during inheritance.

Genes located on the same chromosome always assort together.

Environmental factors determine the expression of all inherited traits.

Alleles of different genes are distributed independently of one another during gamete formation.

Verified step by step guidance

Understand that the principle of independent assortment refers to how alleles of different genes are transmitted to offspring during gamete formation.

Recall that during meiosis, homologous chromosomes are separated into gametes independently of one another, which means the inheritance of one gene's alleles does not influence the inheritance of another gene's alleles.

Recognize that this principle applies to genes located on different chromosomes or those far apart on the same chromosome, allowing for genetic variation.

Eliminate incorrect statements: dominant alleles are not the only ones passed on, genes on the same chromosome can assort together (linked), and environmental factors affect expression but do not determine inheritance patterns.

Conclude that the best description is that alleles of different genes are distributed independently of one another during gamete formation, which is the essence of the principle of independent assortment.
