asap, please

Answer 1

1) Mitosis is the equational division that is both parent cell and daughter cells have the same number of chromosomes, so ploidy does not change via mitosis.

Meiosis is the reduction division, Diploid cell undergoes meiosis and four daughter cells are produced, and each daughter are a half set of chromosomes compared to the parent cell, so ploidy changes via meiosis, Parent cells are diploid but daughter cells are haploid.

so the given statement is False.

2) ploidy is the number of sets of chromosomes, in the haploid cell, there is only one set of chromosomes, in a diploid cell, there are two sets of chromosomes, so ploidy is not the number of chromosomes in the cell. so the given statement is false.

3) the cell cycle progress as G1, S, G2, M phase. DNA replicates during S phase, during between meiosis I and meiosis II DNA do not replicate, so the given statement is True.

4) Same genes are found on the homologous chromosomes, in a diploid cell there are two sets of chromosomes, each chromosome exists as a homologous pair, in the chromosomes in homologous pair the genes, and each homologous chromosomes have alleles of the genes, alleles are different forms of the gene, alleles on different chromosomes can be same or different.

so this statement is True.
