After a thorough analysis of the DNA from 150 university students,a small region of the human X chromosome is found to have three SNP sites.Two of those sites have three different variants,while the third site has four.How many different haplotypes were present in each student's cells?

Question

Quizplus · Accepted Answer

Haplotypes refer to combinations of alleles at multiple loci that are transmitted together. Since the X chromosome does not undergo recombination over most of its length in males (who have only one X chromosome), each male student can have only 1 haplotype for this region. Female students, having two X chromosomes, can have either 1 or 2 haplotypes depending on whether their X chromosomes are identical or different in this region.
