The most common form of hemophilia is a defect in blood clotting factor VIII, which is caused by a mutant form of a gene on the

X chromosome. Boys who inherit that mutation from their mother suffer from uncontrolled bleeding. Girls carrying one copy of this mutation have near normal blood clotting. Uncommonly, a girl is born with hemophilia even though both parents have normal phenotypes. Which of the statements might explain hemophilia in a girl born to parents with normal blood clotting phenotypes?

Answer:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom, she is XO.

Explanation:

Nondisjunction during sperm arrangement and formation brought about her getting no sex-chromosome from her dad and an X chromosome from her mom; she is XO.  

It is on the grounds that her mother happens to be a carrier of hemophilia and she transferred that mutant allele to her daughter and due to the fact that she did not get any sex-chromosome from her dad.

However, such mutant (X) communicates and expresses itself and she is hemophilic.

This (X) is not express in her mother because she possesses a recessive trait; as such it appears in the hom8zygous state.

Scientists and doctors are working hard to find a way to cure cancer. Which cellular process are they studying to try and cure t
Natasha_Volkova [10]

Answer:

<em>The correct option is B) regulation of mitosis</em>

Explanation:

Cancer can be described as a group of diseases which result from uncontrolled, abnormal cell division. The cell division by which the cells divide (except sex cells) is termed as mitosis. Hence, scientists will be studying the regulation of mitosis if they are to find a cure for cancer.

Other options like option A are not correct because only sex cells divide by meiosis. Hence, regulation of meiosis will not cure cancer.
