Answer:
Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.
Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.
When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.
Explanation:
If the concentration of molecules outside the cell is very high relative to the internal cell concentration, the rate of diffusion will also be high. If the internal and external concentrations are similar (low concentration gradient) the rate of diffusion will be low.
Well its a little deeper than that. The oxygen transport is made through Hemoglobin (red blood cells) which is pumped from the heart
Answer:
The correct option is: b. in the different genes
Explanation:
In an organism, complementation is observed when the two strains with the different homozygous recessive mutations are mated or crossed to produce an offspring having wild-type phenotype.
<u>Complementation is observed when the mutations are present in different genes.</u>
<u>Therefore, mutations are said to be</u><u> complementary, </u><u>if they are present in different genes.</u>
If the subject's artery walls were half as thick as they were originally back before 20 years, the most likely long term effect if the measured trend continues is that the arteries and vein will most likely fuse. Giving the effect of the deoxygenated and oxygenated blood to mix.
