Answer:
Hemophilia is a sex-linked recessive disorder in which a person's blood do not clots and he can bleed to death even after minor injuries because blood will keep running due to a small cut.
It is a recessive trait which means that even if one normal gene is present along with Hemophiliac gene, the person will not have the disease and he will be the carrier.
Question: What will be their children’s possible phenotypes?
If a woman who is a carrier for hemophilia marries a hemophiliac man, their genotypes can be denotes as :
Here H, indicate normal gene and small h indicate defected (hemophilia) gene.
Parents: XHXh X XhY
Offspring: XHXh : XHY: XhXh: XhY
Phenotype of offspring:
XHXh: The child will be daughter and normal (25 % chances)
XHY: The child will be son and normal (25 % chances)
XhXh: The child will be girl and Hemophiliac (25 % chances)
XhY: The child will be son and Hemophiliac (25 % chances)
Hope it helps!

E: nitrogen is much more electronegative than hydrogen.
Explanation:
in paulings scale hydrogen is 2.1 and nitrogen is 3...so
nitrogen is much more electronegative than hydrogen.
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
