A daughter has hemophilia, a recessive sex-linked trait. Which are possible genotypes of her parents?

Biology
1 answer:
marusya05 [52]3 years ago
5 0

Answer:

D. XHxh and XHY

Explanation:

since this is the only answer with genes that share a common allele, the answer is D.

In order for a recessive gene to be present, the daughter must have gained the alleles of XHXH, which in this case, is a 25% chance. The other two possibilites are XHxh, XHY, and Yxh. To further prove this, a female must have 2 X alleles and to have hemophilia, they must carry 2 H's. If they were to only have one H, they would be a carrier instead of a product.

Which of the following statements is a false or incorrect statement?
irakobra [83]

Answer:

The correct answer is option d) "damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes".

Explanation:

It is false that damage to the primary motor cortex results only in the loss of both voluntary muscle control and reflexes. Many people that suffer from brain damage by strokes suffer from primary motor cortex damage. This damage not only affects voluntary muscle control and reflexes, as it affects muscles movement of any kind and can affect coordination as well.

A flash flood carried a raft of Amazon ants away from their original population. There is enough distance between the two groups
vitfil [10]

Answer:

geographical isolation

Explanation:

Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.

There are two mechanisms of reproductive isolation:

  • Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation,  geographical isolation and behavioral isolation.
  • Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.

<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>
