reptiles and all birds are oviparous, meaning that their young develop in
fertilized eggs laid outside the mother's body. In contrast, most mammals are
viviparous, meaning that their young develop inside the mother's body.

main difference between these two groups is that oviparous animals do not
undergo any embryonic development inside the mother whereas viviparous do.</span>

The chromosomes are separated by a structure called the mitotic spindle.
A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation.
Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
