Do gametes carry 1 allele or 2 alleles of a gene? Would a sperm cell only have 1 allele to carry?
Gametes are cells involved with the sexual reproduction of complex eukaryotic organisms. They tend to come in two varieties: sperm and egg. When these two cell types meet, they can fuse to form a zygote, which can grow into a fetus and so on.
Answer and Explanation:
Most organisms that perform sexual reproduction are diploid - they contain two copies of their genetic material. Gametes, however, are haploid - they contain one copy. This means that sperm and egg cells only contain 1 allele apiece per gene, instead of two, since there is only half of the genetic material present.
