Chemistry
1 answer:
Wittaler [7]2 years ago
5 0

Answer 1:

This is an example of successful adaptive mutation. Adaptive mutations actually happen because of high levels of stress in the organism's environment caused by the same stressor/s. Here, lots of rabbits being excessively cold all the time due to environment changes caused a lot of extra stress and over time, they successfully mutated to adapt to their environment.

Answer 2:

The answer should be the 4th one. A mutation that doesn't work doesn't always fully go away, but it will become much less common.

A polygene is a member of a collection of non-epistatic genes that interact additively to steer a phenotypic trait, consequently contributing to more than one-gene inheritance, a sort of non-Mendelian inheritance, in preference to unmarried-gene inheritance, which is the core belief of Mendelian inheritance.

A polygenic trait is a feature, which includes height or skin coloration, that is encouraged by way of or extra genes. because a couple of genes are concerned, polygenic developments do not comply with the styles of Mendelian inheritance. Many polygenic traits are also stimulated by means of the environment and are called multifactorial.

Most inherited trends in animals are polygenic. a few examples are: conformation, kind, size, sturdiness, disorder resistance, temperament, velocity, milk and egg production, growth fee, maturation and sexual adulthood rate, and numerous inherited diseases.
