Question

What is the primary genetic danger of prolonged inbreeding and consanguinity in human populations?
Options
A A massive increase in overall genome-wide heterozygosity
B Increased expression of deleterious recessive alleles due to elevated homozygosity
Correct Answer
C Spontaneous conversion of autosomes into sex chromosomes
D Systematic failure of meiotic crossing over across all loci
Correct Answer
