Answer:

A new mutation

Explanation:

A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.

However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.

How does polygenic inheritance differ from mendelian inheritance
Luba_88 [7]

Answer:

Mainly, the number of genes that control traits.

Explanation:

Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.

Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.

Mendelian inheritance would assume that the offspring would either be fair or dark only.

Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.

Hope you understood it.

Can I get some help with 1 and 2
ikadub [295]
For number one, wolves may eat fish instead of larger animals because those larger animals may be going into hibernation and also the berries that a wolf may eat has also gone out of season, leaving the only choice really being fish.

For number two, over harvesting salmon is pretty bad when it comes to the environment. it takes away food from predators, like the wolves in number one, so they lose a source of food and it also takes away the salmons ability to eat the smaller organisms in the stream, so they're going to become overpopulated.

How does wound healing relates to cell division ( i need a paragraph pleasee)<br> HELP ASAP
klio [65]
The process of cell division whereby the chromosomes are duplicated and distributed equally to the daughter cells is called mitosis. The cells stretch out when you get a wound and explode, that is why you have blood but then when more cells are formed it gets tightly together and closes up the wound in which then separates to make more cells.
