Describe the chromosomal difference between sex cells and a zygote (fertilized egg)/ body cells

The main difference between sex cells and zygote is the chromosomal charge, where the sex cells have half of the chromosomes haploid and the zygote has the full load, is diploid, as well as the body cells.

Explanation:

Ploidy is based on the number of chromosomes found in a cell:

The reason for this difference is that the gametes go through a process of reductional division, called meiosis. They are haploid because when the gametes of the parents unite —during fertilization— they give rise to a haploid cell, the zygote.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
