Question

Would each of these chromosomes in the karyotype have sister chromatids or not? 46 chromosomes

Answer 1

Yes.

Step-by-step explanation:

All chromosomes in a cell will have sister chromatids during mitosis.

Each strand of a chromosome is called a chromatide. During mitosis, each chromatide remains linked to another chromatid by the centromere, thus forming the sister chromatids. This happens on all 46 chromosomes in a cell.

Subsequently, the sister chromatids separate, during anaphase, forming chromosomes once again.

Answer 2

Yes

Step-by-step explanation:

Provided that the organism is a diploid organism, each of the chromosomes in the karyotype will have sister chromatids.

Karyotyping is a process of analysing chromosomal constitution of the genome of an organism. The chromosomes are arranged in pairs and orders in which they exist in the organism's genome.

Diploid organisms always have diploid number of chromosomes. The chromosomes occur in pairs with each pair being similar or homologous to each another.

Hence, for a diploid organism with 46 number of chromosomes, the karyotype will consist of 23 chromosomes pairs with each pair consisting of sister chromatids.
