during sexual reproduction, each parent contributes

During sexual reproduction, each parent contributes half of the offspring’s genetic material (half of the chromosomes/genes), so the child ends up with a full set made from both parents.

Quick Scoop

• Each parent contributes one set of chromosomes via their gametes (sperm or egg), which is half the usual number found in body cells.

• In humans, the sperm provides 23 chromosomes and the egg provides 23 chromosomes, giving the zygote a total of 46 chromosomes.

• This “half‑from‑each” pattern means offspring inherit different alleles (versions of genes) from each parent, creating genetic variation.

• Because of this mixing, children resemble both parents but are not genetically identical to either one.

So, if your sentence starter is:

“During sexual reproduction, each parent contributes …”

a clear way to complete it is:

“During sexual reproduction, each parent contributes half of the genes (one set of chromosomes) needed to form the offspring.”
