A cat germ cell has a haploid number of 19 chromosomes.
1) Number of cells in prophase 1 and telophase 1 of meiosis
2) Number of chromatids in prophase 1 and telophase 1 of meiosis
3) Number of chromosomes in prophase 1 and telophase 1 of meiosis
As the germ cell of a cat has a haploid number of 19 chromosomes, so, after the S phase of interphase the chromosomes will duplicate, and thus the number of chromosomes and chromatids will be doubled. This means after the S phase of interphase the chromosome number will be (19×2) = 38 and the chromatid number will be (38×2) = 76. This number will remain constant till telophase 1. After telophase 1, cytokinesis 1 will occur and the cell will be divided into two daughter cells each having 19 chromosomes means 38 chromatids.
Number of cells in prophase 1 | 1 |
Number of cells in telophase 1 | 1 |
Number of chromatids in prophase 1 | 76 |
Number of chromatids in telophase 1 | 76 |
Number of chromosomes in prophase 1 | 38 |
Number of chromosomes in telophase 1 | 38 |
