Occasionally, a gamete is formed that contains both alleles of a gene instead of one. The result is the presence of three alleles of a gene after fertilization. Which of Mendel’s laws would this gamete violate, and when during meiosis would the gamete form?

Question

law of segregation, meiosis I
law of independent assortment, meiosis I
law of independent assortment, meiosis II
law of segregation, meiosis II

Answer 1

The gamete with three alleles of a gene would violate Mendel's law of segregation, which states that each parent contributes only one of their alleles to their offspring. This violation would occur during meiosis I, when homologous chromosomes separate and are distributed into different daughter cells.
