The phenotype is - 75 % red and 25 %brown.
The genotype is hRhR - 25%
hBkhR - 50%
hBrhBk - 25%.
<h3><u>Explanation:</u></h3>
The cross given here is a simple dominant - recessive relationship between the three types of alleles of hair colour. The genes of this characteristics are present in autosomes, so will be segregated equally among all the sexes of the offsprings.
Now the genotype of auburn and red with black mother is given. So during gametogenesis, the gametes from the parents will be
Father - hBr and hR
Mother - hBk and hR
So, the probable combinations are hBrhBk, hBrhR and hBkhR.
The frequency of the combinations are 25%, 25% and 50% respectively.
The phenotypic ratio will be red : brown as 3:1.
Answer:
I believe the answer is A
Explanation:
I think it is A because the original function of the spinal cord is to complex organization of nerve cells responsible for movement and sensation. It carries signals between the brain and the rest of the body.
Answer:
Macroinvertebrates serve several important functions within the aquatic environment:
They provide a valuable "cleaning" service by scavenging dead or decaying bacteria, plants, and animals, which helps recycle nutrients back into the system.
They are an important food for fish, birds, amphibians and reptiles.
Explanation:
the list could go on and on.
Coarctation of the aorta can cause high blood pressure in the heart. This can cause the muscle of the heart's main pumping chamber (left ventricle) to become thick. Eventually, the function of the heart muscle could deteriorate if the condition isn't treated.
Here's what he must do:
-- Run the experiment again, several times if possible. Combine or
analyze
the results of the several experimental runs in some statistically
valid way.
-- Run the simulation again, several times. Combine or analyze the results
of the several simulations in some statistically valid way.
-- Then, compare the analysis of several experimental runs with the analysis
of several simulations, in some statistically valid way, to decide whether they
<em>really</em> don't track.
-- If they do, then look for ways to tighten up the simulation so that maybe
they can track better.
-- If they don't, then he's back to <em>before</em> Square-1. He not only has to
deal with the question of whether or not his experiment is valid, but he
also has to consider the possibility that his simulation is trash and
doesn't actually model nature like he expected it to.
