Question

which scenario breaks the law of segregation?
a gamete contains the fathers allele
the gametes produced each have 1 allele after meiosis ii
a gamete produced has 2 of the same alleles after meiosis ii
the gamete fertilized has the dominant trait

Explanation:

Mendel's law of segregation states that during meiosis, the two alleles of a gene separate so that each gamete receives only one allele. A gamete having 2 of the same alleles after meiosis II violates this law as it should have only one allele. A gamete containing the father's allele is normal as alleles come from parents. Gametes having 1 allele after meiosis II follow the law. A fertilized gamete having the dominant trait is about allele expression (dominance) not segregation.

Answer:

a gamete produced has 2 of the same alleles after meiosis II
