WebApr 21, 2024 · A)Crossing over shuffles genes between non-homologous chromosomes. B)During meiosis, cells arrange their alleles so that beneficial alleles are passed on together. C)Without crossing over, offspring would be genetically identical to parents. WebA. Crossing over shuffles genes between homologous chromosomes so option A is false. B. During meiosis cells arrange their alleles in random manner so both beneficial and non beneficial alleles are passed on together. So option B is false. C. No, Without crossing over offspring would not be genetically identical to their parents.
