Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure cal
led a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
The diploid chromosome number for a radish is 18 and the diploid chromosome number for cabbage is also 18. The haploid number for these species is nine. Therefore, the gametes of the radish and cabbage contain nine chromosomes.
