Compare the similarities and differences between natural selection and artificial selection

Biology
1 answer:
AysviL [449]3 years ago

Similarities: Natural Selection and Artificial Selection both result in the alteration of the gene pool. It can also change phenotypes of different species'.

Differences: Artificial Selection is when a specific trait is not wanted, and so it is not bred.

For example, humans did not like how yellow peas looked. They liked the healthy looking green better. So, they killed the yellow peas, and bred the green peas with other green pea plants, and right now it is almost completely out of our gene pool.

Natural Selection is when something naturally occurs, such as a natural disaster, famine, plague, invasive species introduction.

For example, if 10 camels lived in a desert, but one of them didn't have as good of a metabolism and stayed full longer, then that one would survive, while the others might not.

lesantik [10]

Answer:

The correct answer is A) Histone deacetylation generally decreases gene expression.

Explanation:

Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.

In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.

<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>

A recessive gene located on the X chromosome is the cause of one type of colorblindness (denoted by Xc). Let the genotype for no
Alex73 [517]

The scenario will be Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son

<h3>What is color blindness?</h3>

The condition is frequently inherited. Certain eye diseases and medications are also possible causes. Men are more affected than women.

Color blindness is characterized by the inability to distinguish between red and green shades.

A colorblind man's genotype is XcY, and a heterozygous carrier female's genotype is XcX. A cross between XcY and XcX would result in progeny with the following ratio=

Son: 25% colorblind daughter: 25% colorblind son: 25% of carrier daughters with normal vision: 25% normal son.

Thus, the couple is likely to have a son who is half normal and half affected. Similarly, the couple is likely to have 50% normal daughters and 50% colorblind daughters.
