haploid is 4
diploid is 8
Q 24)
Ans =D= 228
25)]
Total chromosomes 2n= 46 chromosomes
homologs =22 pairs
total Dna molecules = 92 DNA molecules .
autosomes =22 pairs or 44 autosomes.
male /female ==cant answer as the picture is not clear.
Q 26)
B =Meta phase of meiosis 1
homologus chromosomes are arranged on a plane equdistant from the poles .Spindle fibers from each pole attaches to the chromosomes and centrioles are at the opposite sites of the cells.
27) Metaphase of mitosis.
It is the Third stage of mitosis, where cells chromosomes allign themselves for duplication.

Can someone please check my answer? Understanding chromosome number and behavior during cell division is an important concept in genetics. Fill out the chart below for each phase of mitosis in terms of N (where N = haploid number). For example, humans have a haploid number of 23. There are 46 chromosomes (2N) present in prophase of mitosis. Each chromosome is present in its replicated form (i.e. as sister chromatids) so there will be 2 chromatids per chromosome and the...

If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
