Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?​

Answers

Answer 1

Answer:

Genotype of night blind woman -  XnXn

Genotype of normal man - XY

Explanation:

Given

Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive

In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased  . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect

Genotype of night blind woman -  XnXn

Genotype of normal man - XY

Answer:

The benefit of this is let's say theoretically you're mom got small pox at age 10 and gave birth to you at age 35 her DNA was built up to withstand small pox if she gets it again. If a small amount of her DNA is in you then chances are she passed that immunity to you and you have mutation for the better.

Outline the effect of the following mutations:
TAG-> TAT
TAC-> TCC

Answers

Answer:

TAG-> TAT >> sense mutation  

TAC-> TCC >> missense mutation

Explanation:

A sense mutation is a type of mutation that changes a stop codon into a sense codon, thus producing an elongated protein. The TAG codon (UAG in the RNA) is a stop codon, while TAT (UAU) encodes for tyrosine, thereby TAG-> TAT is a sense mutation. On the other hand, a missense mutation is a type of point mutation where a single nucleotide change generates a new codon which encodes a different amino acid. In this case, the TAC codon (UAC) encodes for tyrosine, while TCC (UCC) codon encodes for serine, and therefore TAC-> TCC is a missense mutation (Tyr to Ser mutation).

Explanation:

Anoles are a family of IIzards found throughout the Americas. Green anoles, Anolis carolinensis, are native to i specific area of Florida. In this
area, the primary territory of green anoles was once along the ground and in low-level branches. However, the Introduction of brown anoles,
Anolis sagrei, from Cuba forced green anoles to shift o their territory to the tops of trees. The branches at the treetops are smoother and thinner
than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickler.
What is the best explanation for the change In green anoles' toe pads?
Some individuals In the green anole population had mutations that helped them survive and reproduce In the new conditions,
so thelr genes were passed on to the next generation.
O B. Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and
reproduce, and those tralts were passed on to the next generation.
The feet of the green anoles became larger and stickler as they used them, which helped the green anoles to better survive,
reproduce, and pass the tralt on to the next generation.

Explanation:

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?

Answers

Answer:

The correct answer is - as energy lost at every trophic level.

Explanation:

In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.

The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.

As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.

In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.

Thus the response above is right.
