Phenotypically and genotypically there are only two different ratios. If you think of a Punett square... 

<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>

<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>

<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>

<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>

Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.

Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.

The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.

In fruit flies, one genotype for red eyes is written XRXR. The R stands for the dominant allele for red eyes. What does the X st
Reil [10]

Answer:

The correct answer is : the female chromosome

Explanation:

  • According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
  • RR is a genotype for Red eyes.
  • A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
  • In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
  • Therefore, XX must represent another trait.
  • By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
  • Given XX genotype represent a female fruitfly chromosome.
