In a human gamete there are 23 separate DNA molecules resulting from. meiosis and are called "daughter chromosomes" and are essentially chromatids.The parent cell has 46 duplicated chromosomes = 92 DNA molecules (92 chromatids). After meiosis 92/4 = 23 per cell.

A gamete has 23 chromosomes no longer chromatids A chromatid is a million/2 a chromosome. a usual human cellular has 40 six chromosomes (23 pairs) A cellular with 40 six chromosomes splits in 2 to type 2 gametes. A gamete has 23 chromosomes so as that as quickly as 2 gametes connect (23+23) there are 40 six chromosomes.

Are you talking about meiosis? DNA replicates during interphase - the number of chromosomes stay the same, but the number of chromatids don't (doubled).

Peter answered it right. Nope a homologous pair only has 2 chromosomes duplicated into another two.
Father chromosome duplicated and the mama chromosome duplicated.
Father chromosome duplicated and the mama chromosome duplicated.
參考: hope this helps :)
