Respuesta :
two members of an allelic pair of genes separate during gamete
Answer : The correct answer for the blank is-
The two members of an allelic pair of genes are separated from one another during gamete formation.
According to Mendel's law of segregation, during formation of reproductive cells (gametes such as sperms and eggs) in sexually reproducing organisms, variants of a gene (alleles) are separated from one another so that every gamete carries single allele for the trait.
This law is also known as law of purity of gamete.
