Question 12 • CMS 2026-2027 Biology CREDIT RECOVERY

Which scenario breaks the law of segregation?

Answer
A
the gametes produced each have 1 allele after meiosis II
B
a gamete produced has 2 of the same alleles after meiosis II
C
the gamete fertilized has the dominant trait
D
a gamete contains the father’s allele

Explanation

The law of segregation says the two alleles for a gene separate during gamete formation, so each gamete receives just one allele. Choice B says a gamete has two copies of the same allele after meiosis II, which breaks that rule. Having one allele, inheriting the father’s allele, or carrying an allele that produces a dominant trait does not violate segregation.
