One explanation could be cross-breeding. A hominid outside of Africa could have bred with Neanderthals and migrated to Africa afterwards, thus having offspring in Africa that has Neanderthal DNA.
Answer:
0.4550
Explanation:
In this example, R allele is dominant, so individuals RR and Rr can roll their tongues. If in a population of 1000 gorillas, there are 575 gorillas who can roll their tongues, they will be RR and Rr.
In this case, there is Hardy Weinberg Equilibrium, so the following will be true:
Where:
frequency of RR
frequency of Rr
frequency of rr
The question is what is the frequency of heterozygotes, or, what is the value of 2pq.
We know that RR+Rr is 575 individuals in a population of 1000, or 0.575.
In other words:
So, it is possible to find :
Now, there are two alleles in the population, so the following will be true:
It is possible to find q (the frequency of allele r) and p (the frequency of allele p):
Therefore:
Now, the frequency of heterozygotes or 2pq is:
Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
Know what happens? P.S. If it doesn't help sorry
Answer-Because when fossil fuels are burned,the fossil fuels are running out more and more and so sientists are trying to figure out a way for fossil fuels to become more of a renewable resources then a nonrenewable resource so that we have more of a likely cause that we will have a future use of all the fossil fuel that are about to run out just like an extinct species.
Your welcome if it worked!
Hi!
Could you please be more specific, so that I can answer your question properly? Layer of what?
