Question

List three separate phenomena that occur during meiosis and fertilization that contribute to genetic uniqueness A. random assortment, crossover and which gamete contributes to the zygote B. the number of cell divisions, how tightly the DNA is coiled and the number of chromosomes C. mistakes made during DNA replication, repair of those mistakes, and apoptosis

Answer 1

Answer:random assortment, crossover and which gamete contributes to the zygote

Explanation:Genetic uniqueness is increased by meiosis

During fertilisation, 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.
