The law of segregation states that
A.the two alleles for a trait separate into different gametes
B.alleles stay together through gamete formation
C.all genes assort as one unit
D.dominant alleles are always more frequent
Explanation
Core Concept
Each gamete receives one allele per gene because homologs separate in meiosis I — the physical basis of Mendel's 3:1 ratio.
Correct Answer
Athe two alleles for a trait separate into different gametes
