Please answer and I will give good rating

You have identified a new species of fruit fly and adults have 6 chromosomes. You also discover that this species performs mitosis and meiosis as other eukaryotes. Based on this information how many chromosomes will you expect to find in the following cells.

Mitotic cells just entering G1

Meiotic cells just entering G2

Meiotic cells having completed MI

Mitotic cells during anaphase

Meiotic cells during anaphase II

Solutions

Expert Solution

Mitotic cells just entering G1 = 6 chromosomes

Meiotic cells just entering G2 = 6 chromosomes (but 12 chromatids)

Meiotic cells having completed MI = 3 chromosomes (but 6 chromatids)

Mitotic cells during anaphase = 12 chromosomes

Meiotic cells during anaphase II = 6 chromosomes

Explanation:

Mitotic cells just entering G1

The cells that are entering G1 have diploid number of chromosomes. So, number of chromosomes = 6

Meiotic cells just entering G2

The cells entering G2 have already gone through DNA replication at G1. Each chromosome has two copies (sister chromatids) each. However, the two copies are linked at centromere and are hence considered as one single chromosome. Hence, although chromatids are 12, chromosomes are 6

Meiotic cells having completed MI

Meiotic cells that have completed Mitosis I have only one type of each homologous pairs. Hence, the number of chromosomes is 3 (haploid). However, each chromosome exists as two sister chromatids joined together. So, chromatid number is 6

Mitotic cells during anaphase

During anaphase (mitosis), the sister chromatids separate. However, the cell has not divided completely. Hence, the cell consists of 12 chromosomes.

Meiotic cells during anaphase II

During Anaphase II, in the haploid cell, the sister chromatids separate. However, the cell has not divided completely. Hence, the number of chromosomes are 6

7. You have identified a new species of nematode that you are interested in studying and understanding its early development. In particular, you want to know if the same factors responsible for establishing early differences between cells are the same between this nematode and C. elegans.
