What is primary and secondary constriction?

Primary constriction refers to the central region of a chromosome where the two sister chromatids are joined, known as the centromere. It plays a crucial role in the proper segregation of chromosomes during cell division. Secondary constriction, on the other hand, is a region outside the primary constriction, often associated with the nucleolar organizer regions that contain genes for ribosomal RNA. This secondary constriction can be involved in the formation of nucleoli during interphase.


What is a sat chromosome?

A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.


What is the difference between primary and secondary nondisjunction?

primary can happen in meiosis and as a result produces gametes with more than or less than the original number of chromosomes. secondary occur in an individual whose chromosomes already has the wrong number because of non disjunction.

How many chromosomes in a spermatid?

A spermatid contains 23 chromosomes, which are the result of meiosis dividing the original diploid germ cell's 46 chromosomes in half. This reduction in chromosome number ensures that when the spermatid fuses with an egg during fertilization, the resulting zygote will have the correct number of chromosomes.
