Given RRYY x Rryy, what will the parents be? (no links please)

Biology
1 answer:
Tema [17]3 years ago
5 0

I'm guessing the genotypes given (RRYY x Rryy) are the offspring (if this isn't the case this answer may be wrong)

RRYY has both dominant alleles. So we can safely say that the parents are both RRYY.

For Rryy :

Rr is heterozygous (the alleles are not the same), so the parents could be:

RR x rr

RR x Rr

Rr x Rr

(if you do a small punnet square, you can double check these!)

Since yy has both recessive alleles, the parent is yy as well.

Select all that apply. What characteristics do mutations have?
Vinil7 [7]
Well mutations can be a positive or a negative feature. Some mutations can be used as a camouflage so stay safe from predators. Other mutation could give off a bright color which would make it hard to stay hidden from predators.

You have identified a previously unknown human gene that appears to have a role in autism. It is similar enough in DNA sequence
nexus9112 [7]

Answer:

Amino acid sequences

Explanation:

The proteins perform the vast majority of functions in the cells. If a gene between a human and a mouse is evolutionarily related, it means that the function they do in the cell is quite similar in both species. This is the reason why the amino acid sequence would be the most similar.

In addition, there might be certain mutations in the DNA and therefore in the RNA between this 2 sequences that encode to the same amino acid sequence. More specifically speaking, there are more than one codon that encode to the same aminoacid. Thus, 2 different DNA/RNA sequence can give the same aminoacid sequence.

What is the difference between a solar flare and solar wind?
mezya [45]

The biggest difference is the cause. The solar wind is a constant flow of particles from the sun's corona due to their high energy gained from the sun's interior, it's like being boiled off. CME's and flares are the result of “explosive” releases of energy from the sun's magnetic field. Solar flares and solar winds originate within the sun's atmosphere, but differ greatly from one another. Satellites on Earth and in outer space allow a look at solar flares, but you cannot see solar winds directly. However, the effects of solar winds reaching Earth appear to the naked eye when the aurora borealis and aurora australis electrify the night sky.
