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:

The law of segregation states that during gamete formation, the two alleles of a gene segregate so that each gamete carries only one allele for each gene. Let's analyze each option:

• "a gamete contains the father’s allele": This is normal as gametes can carry alleles from either parent.
• "the gametes produced each have 1 allele after meiosis II": This follows the law as gametes should have one allele per gene after meiosis.
• "a gamete produced has 2 of the same alleles after meiosis II": This breaks the law because gametes should have only one allele (after proper segregation) and having two of the same alleles here indicates a failure in segregation.
• "the gamete fertilized has the dominant trait": The trait of a fertilized gamete (zygote) doesn't relate to the segregation of alleles during gamete formation.

Answer:

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