<span>The right answer is D. males have only one copy of the X chromosome.
</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>
The answer to the is hypothermia
"The ability of an organism to react to an environmental input with a change in form, state, movement, or rate of activity" is a definition of Phenotypic Plasticity.
<u>Explanation:</u>
The tendency of one genotype when opened to different conditions, to create more than single phenotype is called as "Phenotypic plasticity".It's the secret to studying human behaviour.
It's the key to human conduct study by laying the foundation to take into consideration the concept that the similar genome and the similar neural architecture will lead to human cultural diversity. For plants whose sessile existence needs them to survive with environmental conditions, this capacity is especially important.
So that it can sustain different life that requires different environments. Angler fish, for example, require a dark and cold environment to thrive while tuna require a light and warm environment.
