Does the dna of the sperm and egg join together and then replicated?If not,then what happens?
Asked by | 06 Oct, 2012, 08:09: PM
Expert Answer
During fertilisation, the fusion of sperm and ovum forms the zygote. Here intermingling of two sets of haploid genes (male and female) occurs to reconstitute a diploid cell. The diploid zygote then divides, during which the chromosomes are also replicated.
