Harry and Larry are identical (monozygotic) twin biologically male humans. Sara and Kara are identical (monozygotic) twin biologically female humans. In the absences of mutations, if Harry and Sara had a daughter (cross 1), and Larry and Kara had a daughter (cross 2), would we expect the daughter zygotes to have identical genotypes?
Question 11 options:
Yes, because the genotypes of biological fathers and mothers, respectively, would be the same in cross 1 and cross 2
No, because recombination would result in unique gametes in both crosses/parents
Yes, because in sexually reproducing species, each parent must contribute 50% of their genome to each offspring
No, because the parent genotypes are all unique
No, because of differences in environment/nongenetic factors between cross 1 and cross 2
