Mendel's concept of segregation implies that the two members of an allelic pair of genes:

The correct option is A

are distributed to separate gametes

The correct option is A.

Explanation of the correct option :

1. In Mendelian genetics, in a given plant or animal each character is governed by two alleles, one coming from the father and one coming from the mother.
2. At the time of gamete formation both the alleles, of each gene, separate from each other and go to separate gametes.
3. Thus, each gamete will be having only one allele from each pair of the allele, e.g., for tallness if we denote two alleles in a plant as Tt then that plant can form two possible gametes one having T and the other having t allele.

Final answer: Mendel's concept of segregation implies that the two members of an allelic pair of genes are distributed to separate gametes.
