Complete the following sentences on the three ways sexual reproduction ensures genetic diversity. Recombination of _______ on chromosomes occurs during _______ of meiosis through a process called . Essentially, this process involves exchanging pieces of their DNA. developing _______ and then separating with the same amount of DNA they started with. During _______ of meiosis. maternal and paternal chromosomes are randomly assorted to produce daughter cells through a process called During _______ reproduction. _______ (i.e.. an egg and a sperm) unite to form s zygote through _______ . The enormous genetic variability among eggs as well as sperm make every zygote unique.Explanation / Answer
Answer:
1. Recombination of alleles on chromosomes occurs during prophase I of meiosis through a process called Crossing over. Essentially, this process involves homologous chromosomes exchanging pieces of their DNA, developing chiasmata and then seperating with same amount of DNA they started with.
2. During metaphase I of meiosis, maternal and paternal chromosomes are randomly assorted to produce daughter cells through a process called segregation.
3. During sexual reproduction, gametes (ie., an egg and a sperm) unite to form a zygote through fertilization .The enormous genetic variability among eggs as well as sperm make every zygote unique.
