The given diagram of separation of alleles during gamete formation examples the:

Correct answer: D. Mendel's law of independent assortment

  • A. Sex-linked inheritance
  • B. Inheritance of a single trait
  • C. Hardy-Weinberg principle
  • D. Mendel's law of independent assortment

Explanation

The correct answer is Mendel's law of independent assortment. This principle explains that alleles of different genes assort independently during gamete formation, which is depicted in the diagram of separation of alleles. The law is fundamental to understanding genetic variation. The other options are incorrect as they describe different genetic principles: sex-linked inheritance relates to genes on sex chromosomes, inheritance of a single trait focuses on Mendel's law of segregation, and the Hardy-Weinberg principle pertains to population genetics, not individual allele separation during gamete formation.

About Mendel's Laws of Inheritance

Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
