Question
How many autosomes are present in a normal human cell?
- 22
- 44
- 23
- 46
Hint:
44
The correct answer is: 44
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46. 22of these pairs, called autosomes, i.e., 44 autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

Which of the following is NOT an example of intra-genic gene interactions?
- Example of epistasis is fur color. The fur color of an animal depends on two genes (E and B). B gene is responsible for color while E gene determines the level of expression of the B gene.
