If someone with auburn hair has children with someone with red hair (but whose mother had black hair ) what are the genotype and
tensa zangetsu [6.8K]

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.

If the arota of the heart is damaged, which function of the heart will be affected first?​
Alisiya [41]

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.

After a recent experiment, a
bija089 [108]
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.
