An individual is heterozygous for a gene at a specific locus. will have the same form of alleles at that locus after S phase. A. Sex chromosomes. B. Homologous chromosomes. C. Non-sister chromatids. D. Sister chromatids.

D

Explanation:

Sister chromatids will have the same form of alleles at the locus after S phase.

This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.

The correct option is D.

the answer is definitely 36.

hope this : )
