What are some examples of genetic diversity.?

Biology

Andrej [43]3 years ago

Answer:

As females mate more often with males considered to have more favorable traits, these genes occur more often in a population over time. A person's skin color, hair color, dimples, freckles, and blood type are all examples of genetic variations that can occur in a human population

Explanation:

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments.

sweet-ann [11.9K]

Answer:

This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.

Explanation:

  • Due to splitting of the population,
  • The sub-population of rodents formed in Island B are B1 and B2.
  • The sub-population of rodents formed in Island C are C1 and C2.
  • In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
  • In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.

Answer:

"The function of DNA is tied to its structure. ... The bonds between nitrogenous bases are essential to DNA's double helix structure, which resembles a twisted ladder. The base pairs form the rungs of the twisted ladder, and the sugar-phosphate strands form the sides."

Ber [7]
A hypotonic solution<em /> would cause the bacterial cell to lyse or burst. This happens via osmosis. When the concentration of solutes is higher inside the cell, water will move towards that higher concentration because it tries to balance things out. When a lot of water gets into the cell and it can no longer handle it anymore, it will burst or lyse.

Describe the path that oxygen travels when you breathe.
lesya [120]

Answer:

The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.
