Meiosis and fertilization can result in a trait like sickle cell being expressed in offspring because meiosis transfers genetic characteristics from parent to offspring.

<h3>How sickle disease transfers from parents to offspring?</h3>

Sickle disease is inherited when a child receives two sickle cell genes which is one from father and the other from mother. Meiosis and fertilization can result in a trait like sickle cell being expressed in offspring when not expressed in either parent because meiosis transfers genetic characteristics from parent to offspring.

The Florida Panther is the brown and gray species the puma family. For years a small population of the panther lived in the wood
Tasya [4]

The correct answer is - a. It will reduce genetic diversity.

The pumas that live in Florida, also known as the Florida Panthers, will have a much reduced genetic diversity. The reason for this is that the population is very small. It also lives in the same area, where the living conditions are the same. The genetic pool is very small, and the breeding is going on between individuals that have the same traits, and are also relatively closely related, as the mating occurs between the second or third generation that came out form the same parents. That will result in a very reduced genetic diversity, so the Florida Panther will remain the same if the conditions do not change drastically, or these an invasion of pumas from the west into their territory.

Studentka2010 [4]

Answer:

The single nucleotide mutation affects the splicing of the mRNA molecule of Smilin in unhappy people. This with result in a truncated protein lacking part of it amino acidic chain

Explanation:

It's true that the information of aminoacids that form the proteins is codified on the exons, but introns also have important information, for example, the sequences related to the splicing of the mRNA exons.

Briefly, during the splicing process, the introns are removed, leaving the mRNA that is going to be translated (there could be also other post translational modifications before going to ribosomes).

Also, there's different ways to splice the different exons. For example, let's say a mRNA has four exons, so the mature mRNA could have exons 1-2-3-4, or 1-2-4, or 1-2-3, it depends on the location of the splicing signals. This are called splicing alternatives, so the same original mRNA can give arise to different forms of a protein.

In the particular case of Smilin, apparently the DNA has a single mutation in the intron for the mRNA of the protein. Despite it might seem as a minor difference, it causes the final mRNA (the one that is translated) to lose an internal stretch of 173 nucleotides.

A possible explanation is that this single mutation is affecting a splicing signaling sequence, making the splicing complexes skip one exon. Again, if we imagine that the original protein has four exons, this means that the happy people has an mRNA with all the exons, while unhappy people is lacking one.

As a result, the protein Smilin will be lacking part of its internal region. The actual effects this has on the protein function will depend on the role of the deleted section.
