How many chromosomes does each parent donate to the next generation?

How many chromosomes does each parent donate to the next generation?How many chromosomes does each parent donate to the next generation?
Since humans have 46 chromosomes, and the parent organisms each give half of their chromosomes to their offspring, then each human parent would give 23 chromosomes.


It varies for other organisms; basically, you take the number of chromosomes in a regular (diploid) cell and divide it by two.


In sexually reproducing organisms, the 23 (for humans) chromosomes to be passed on the the next generation are held inside gametes, or sex cells. For males, this is the sperm cell, and for females, this is the egg cell. When the egg and sperm meet, the 23 chromosomes from each cell recombine to form a single cell with 46 chromosomes, which is called a gamete and divides many times to produce a baby.





I hope that helps!!How many chromosomes does each parent donate to the next generation?
Each parent donates the haploid number, which is 23, and that totals to 46 chromosomes in the child. The 23 chromosomes cannot be chosen they are completely random genes that get passed down and paired up for the new child.
the haploid number , that means half of the parents chromosomes.
