Daughters get one X gene from each parent.
If the father is a normal male, he carries only a normal X-gene.
Therefore the daughter will always get a normal gene from the father, and a 50% probability getting an affected gene from the mother, therefore 50% chance of becoming a carrier. The other 50% she will inherit a normal X-gene from each parent, thus a healthy female.
In conclusion, no daughter will have haemophilia from a carrier mother and a normal male.
(however, sons will have a 50% chance of inheriting affected X-gene and hence will have haemophilia).

==> starch
13. Which element is present in all amino acids, but not necessarily in fats or carbohydrates?
==> nitrogen

Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.
Answer: Incomplete dominance
Explanation: Incomplete dominance is a type of inheritance, specifically a type of intermediate inheritance when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism’s resulting physical appearance shows a blending of both alleles. The result is a phenotype (expression) where the expressed physical trait is a combination of both of the phenotypes that belong to the alleles. One allele doesn’t mask or dominate the other alleles in this instance. It is also called semi-dominance or partial dominance.
In short, incomplete dominance is when neither gene is fully dominant, and the result is a brand new trait.
The Punnett square shows genetic inheritance as a simple model with only two different versions of alleles: dominant and recessive. In this simple relationship, dominant alleles always override the recessive alleles to be expressed in the organism’s appearance or phenotype. It was created by Gregor Mendel and was important because it contradicted popular ideas at the time that the traits of the parents were simply permanently blended within their offspring. However, modern biologists have discovered that inheritance isn’t as simple as this model would suggest.
An example of incomlete dominance in humans would be hypercholesterolemia.
