Question

If a diploid gamete is combined with a haploid gamete then a zygote (new organism) is created which has a set of chromosomes?

Answer 1

When the two gametes combine, they merge the two sets of chromossome to create a cell with the total number of chromosomes needed to develop, known as a diploid cell. In humans when the haploid sperm and egg cell join in fertilisation the resulting zygote has a total of 46 chromosomes the correct number to develop.
