Questions 1-10: Read the direction below, then complete the table by filling in the numb ers requested. These values will serve as the answers for questions 1-10, respectively. A female member of an animal species has a DIPLOID chromosome number of s0. Use this information to fill out the following table. Situation Number Chromosomes in an oogonium Chromosomes in a ovum (unfertilized egg) Chromatids in a cell in metaphase of mitosis Chromatids moving to EACH pole in anaphase of mitosis Chromosomes in a cell in metaphase of meiosisI Chromosomes moving to EACH pole in anaphase I of meiosis | Chromatids in a cell in metaphase of meiosis lI Chromatids moving to EACH pole in anaphase of meiosisII DNA molecules in a cell in Gi of the cell cycle DNA molecules in a cell in G2 of the cell cycle 5 O 25 100 100 50 5 50 o 5 0 100Explanation / Answer
Oogonia are diploid and will have 50 chromosomes in this case . In the process of oogenesis they become the primary oocytes in fetal ovaries.
The ovum will have half in this case it’s 25 and the sperm has the other half . Then when a zygote is formed the diploid number will be present in it .
Metaphase is the third phase in mitosis in which the all the nuclear material comes together in the cell’s central area and duplication of the genetic material occurs and yes it is all condensed but lesser when compared to anaphase . As it is doubled so the answer here is 100.
50 chromosomes will go to each pole because in anaphase also duplication has occurred . As each chromosome has two chromatids so the answer here is 100.
