Question

Two siblings, Lillian and Natalie, have the same mother and father and look very much alike, but are not twins. They are curious how much genetic information is shared between them. Although siblings can be phenotypically similar, what is the primary reason for siblings not being genetically identical? Random mating between parents creates an increase in genetic diversity, resulting in nonidentical siblings Genomic mutations caused by the environment cause the allelic differences between sibling genomes. meiosis produces gametes with different combinations of parental alleles o Postive selecion between siblingscreates genetic diversity between their respective genomes. Determine the average percent DNA shared betwee Number

Explanation / Answer

C. Recombination in meiosis produces gametes with different combinations of parental alleles

sons and daughter are always 50% related to mom and 50% to dad. So siblings share around 50%of their DNA,
