Question

Recessive mutations occur due to a ___________ of function, while dominant mutations occur due to a ___________ of function?

1) Loss, Gain
2) Gain, Loss
3) Decrease, Increase
4) Increase, Decrease

Answer 1

Recessive mutations occur due to a loss of function, while dominant mutations occur due to a gain of function. For example, a recessive mutation may result in the loss or reduction of a protein's normal function, leading to a genetic disorder. On the other hand, a dominant mutation may cause a protein to acquire a new function or increase.

Step-by-step explanation:

Recessive mutations occur due to a loss of function, while dominant mutations occur due to a gain of function. For example, a recessive mutation may result in the loss or reduction of a protein's normal function, leading to a genetic disorder. On the other hand, a dominant mutation may cause a protein to acquire a new function or increase its activity, resulting in abnormal cell growth or other physiological changes.
