Hemophilia B, a blood clotting disorder, is an X-linked recessive trait. What is the expected percentage of offspring with hemop
Lemur [1.5K]

Answer:

The correct answer is 25%.

Explanation:

Considering that Hemophilia B is an X-linked recessive disease, than for it to be observed in female offspring, the mother must be homozygous recessive because females have XX chromosomes and if the father transfers only the dominant gene then the female offspring will always be heterozygous dominant.

In the case of a father who carries the dominant gene on his X choromosome and a mother who is heterozygous for the disease meaning she has both the dominant and the recessive gene, if we calculate the percentages for this situation, we see that for the first generation, one female offspring is heterozygous dominant, one female offspring if homozygous, one male offspring carries the dominant gene on his X chromosome and the other male offspring carries the recessive gene on his X choromosome which is the one that carries the disease.

I hope this answer helps.

Nadya [2.5K]
Ichthyology is best characterised as Science. None of the other field of studies apply to Ichthyology.

Pseudoscience are beliefs or theories that have been considered scientific. However, they are disapproved scientifically because lack of facts and evidence.

Cryptozoology is study of animals that are rumoured to exist. (Bigfoot, Loch Ness Monster, etc) It is connected with pseudoscience.

Mythology can refer to myths or the study of myths.

As you can see, the study of fish does not apply to any of the area of studies except for Science. Ichthyology applies to Science, because it is a scientific study is different aspects of various species of fish. This includes history, behaviour, and growth.
