49. Oct. 17 th 2011 Dry Erase Review Mrs. Fillpot 504 The offspring produced from sexual reproduction show more variety in their genotypes and phenotypes. Why?

50. Oct. 17 th 2011 Dry Erase Review Mrs. Fillpot 504 The offspring produced from sexual reproduction show more variety in their genotypes and phenotypes. Why? In sexual reproduction, the offspring get one allele from each parent for each trait. There are many more possibilities for genotypes and therefore phenotypes. In asexual reproduction the DNA is exactly like the parent. There is no variation in genotype or phenotype.
