Seems like a lot,

only numbers necessary,

posting out of desperation and insufficient time,

thanks for any help.

Given an organism that has a total of 20 chromosomes in the nucleus of a zygote a. How many chromosomes are present in a cell in G1? G2? b. How many homologous pairs are present in G1? G2? 20 of 141 c. How many sister chromatids are present in G1? G2? d. How many DNA molecules are present in G1? G2? e. How many chromosomes are present in metaphase of mitosis? f. How many DNA molecules are present in metaphase of mitosis? g. How many chromosomes are moving to each (i.e. one) pole during anaphase of mitos h. How many homologous pains are present in the resulting daughter cells of mitosis? How many chromosomes are present in a primary spermatocyte or oocyte? j. How many chromosomes are present in a secondary spermatocyte or oocyte? k. How many homologous pairs of chromosomes are present in a primary spermatocyte oocyte? l. How many homologous pairs of chromosomes are present in a secondary spermatoc or oocyte? m. How many chromatids are present in a secondary oocyte? n. How many DNA molecules are present in a secondary spermatocyte or oocyte? o. How many chromosomes are present in a sperm (or egg)? p. How many chromatids are present in a sperm (or egg)? q. How many homologous pairs are present in a sperm (or egg)? r. How many DNA molecules are present in a sperm (or egg)?
