Question

In sexual reproduction, how many genes does an offspring receive for each trait? ​

Answer 1

Each parents gives of half of the genes acquired by the offspring. 46 chromosomes or 23 pairs.

Step-by-step explanation:

". 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. This makes gametes different from other cells in the body. A basic human body cell contains 46 chromosomes, but the egg and sperm only contain half that number, or 23 chromosomes. Why? Well, when an egg and a sperm come together, which is a process called fertilization, they contribute 23 chromosomes each. Add 23 and 23 together, and you get one happy 46-chromosome-containing fertilized egg that can now develop into a new human.

Meiosis

Gametes are produced by a type of cell division known as meiosis. It's meiosis that reduces the number of chromosomes in the cell down to 23. It's also meiosis that makes gametes genetically different from one another. After the cell division takes place, each sperm and each egg has its own unique genetic makeup. In other words, meiosis can be thanked for giving Junior his cute mismatched ears. "

Answer 2

__________

Step-by-step explanation:

In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.
