Why do you have two copies of every gene?

Answer 1

Because each parent gives you one chromosome in each pair, you have two of every gene (except for some of the genes on the X and Y chromosomes in boys because boys have only one of each).

Some characteristics come from a single gene, whereas others come from gene combinations. Because every person has from 25,000 to 35,000 different genes, there is an almost endless number of possible combinations!

Answer 2

Having two copies of each gene, one inherited from each parent, provides redundancy and genetic diversity in case one copy has a mutation. This redundancy helps to ensure organism survival and adaptation to changing environments. Additionally, having two copies allows for genetic recombination during meiosis, which contributes to genetic variation in offspring.

Answer 3

You inherit two alleles from each parent. :)

Answer 4

Because we get one copy from Dad (sperm) and one copy from Mom(egg). This produces a uniquely different individual.

Answer 5

Because
