They exist because all these genes have descended from the genes of common ancestors.

What does nucleus mean in plants and animals?

In both plants and animals, the nucleus is a membrane-bound organelle that contains the genetic material (DNA) of the cell. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The nucleus is essential for the growth, development, and reproduction of both plant and animal cells.


Why do people have different thumbprints?

People have different thumbprints due to variations in the ridges and patterns formed on the skin during fetal development. These unique patterns are determined by a combination of genetic and environmental factors, making each person's thumbprint distinct.


Why did Edward B. Lewis win The Nobel Prize in Physiology or Medicine in 1995?

The Nobel Prize in Physiology or Medicine 1995 was awarded jointly to Edward B. Lewis, Christiane Nusslein-Volhard and Eric F. Wieschaus for their discoveries concerning the genetic control of early embryonic development.


What are fingerprints the result of?

Fingerprints are the result of unique ridge patterns found on the tips of a person's fingers and palms, formed during fetal development. These ridge patterns are determined by a combination of genetic and environmental factors, making each individual's fingerprints distinct.


What is the Ultimate control of testes development?

The ultimate control of testes development lies in the genetic factors that determine the development and differentiation of male-specific structures. The presence of the Y chromosome, which carries the SRY gene, triggers the development of testes in embryos. These testes then produce hormones, such as testosterone, which further shape the development of male reproductive organs and secondary sexual characteristics.


Do mutations result in changes in genetic patterns?

Yes


What contributes to genetic variation?
