Question

Name two human traits that show variations.

Answer 1

Variations:

1. The difference between two members of a species is referred to as variation. During meiosis, mutation and recombination produce genetic variety.
2. Different skin colors, Eye colors, height, and illness resistance are examples of the traits in which variations can be seen.
3. Mutations that are harmful can result in cancer or genetic diseases. A genetic disorder is a condition brought on by a change in one or more genes. Cystic fibrosis is a human example. A single gene mutation causes the body to create thick, sticky mucus that obstructs digestive organ ducts and clogs the lungs.
4. The factors that affect the variations in humans are environmental factors, genetic factors as well as cultural factors.
