In sexual reproduction, the offspring receives ____ percent of the genetic material of each parent.

25
B
50
C
75
D
100
Explanation: 

Detailed explanation-1: -These cells are called gametes, but you might know them as sperm and egg. Each gamete contains half the number of chromosomes, or genetic material, of the organism. So, each sperm contains 50% of the father’s genes and each egg contains 50% of the mother’s genes.

Detailed explanation-2: -Sutton demonstrated that the number of chromosomes was reduced in spermatozoan cell division, a process referred to as reductive division. As a result of this process, each gamete that Sutton observed had one-half the genetic information of the original cell.

Detailed explanation-3: -To form a fetus, an egg from the mother and sperm from the father come together. The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby’s DNA comes from the mother and half comes from the father.

Detailed explanation-4: -Children inherit 50 percent of their DNA from each parent, but unless they’re identical twins, they don’t inherit the same DNA as each other. If your parents’ genes combined were a deck of 52 cards, you’d receive 26 of them.

Detailed explanation-5: -Sperm and eggs are sex cells. Meiosis is the start of the process of how a baby grows. Normally, meiosis causes each parent to give 23 chromosomes to a pregnancy. When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes.
