Homework SourseA diploid somatic cell from an alien species has a total of
A diploid somatic cell from an alien species has a total of 64 chromosomes (2n = 64). As in humans, one pair of sex chromosomes determines gender: XX in females and XY in males. All other chromosomes are considered to be autosomal. The total number of telomeres in the alien cell in G1 is _______, and the total number of DNA molecules present in the cell at the beginning of prophase II of meiosis is _______. The total number of chromosomes in an alien gamete would be _______.
Solution
Each chromosome has 2 telomeres. So the total no.of telomeres in alien cell in g1 is 128.
Total no.of dna molecules at the beginning of prophase II of meiosis is 64 ( 1 dna molecule = 1 chromatid, 1 chromosome = 2 chromatids)
The total number of chromosomes in an alien gamete would be 32.
Gamete is equal to n.
At the end of meiosis 4 gametes are formed from each cell having ploidy of n.
