Question

which scenario breaks the law of segregation?
○ a gamete contains the father’s 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 don inant trait

Explanation:

The law of segregation states that during gamete formation, alleles separate so each gamete gets one allele per gene. A gamete with 2 of the same alleles after meiosis II (where sister chromatids separate, so each gamete should have one allele) breaks this law. Other options follow segregation: gametes can have father’s allele, have one allele after meiosis II, or a fertilized gamete having dominant trait is normal.

Answer:

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