In the first stage o sexual reproduction, "meiosis", the nummer o chromosomes is reduced frae a diploid nummer (2n) to a haploid nummer (n). During "fertilisation", haploid gametes come thegither tae form a diploid zygote an the oreeginal nummer o chromosomes is restored.

Sexual reproduction is a form o reproduction whaur twa morphologically distinct teeps o specialized reproductive cells cried gametes fuse together, involvin a female's lairge ovum (or egg) an a male's smawer sperm.
