In notice as I move through the list the chromosomes get smaller and smaller in size and a little disfigured. … These two chromosomes are different as chromosome X is much larger than the Y chromosome.

How are male karyotypes different from female karyotypes?

Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.

Can chromosomes be altered?

In addition to chromosome losses or gains, chromosomes can simply be altered, which is known as structural abnormality. Many structural abnormalities exist. A translocation occurs when a piece of one chromosome breaks off and attaches to another chromosome.

How chromosome affects the characteristic of species?

When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.

What are the different structural changes happening during each stage of cell cycle?

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
