C
the egg
Verified step by step guidance1
Understand that a zygote is the initial cell formed when a new organism is conceived, resulting from the union of a sperm cell and an egg cell.
Recognize that human cells typically contain 46 chromosomes, which are organized into 23 pairs.
Each parent contributes one chromosome to each pair, meaning the sperm from the father provides 23 chromosomes and the egg from the mother provides 23 chromosomes.
Combine the chromosomes from both the sperm and the egg to form the complete set of 46 chromosomes in the zygote.
Conclude that the 46 chromosomes of a zygote come from both the mother and the father, as each parent contributes half of the genetic material.
