professor190 [17]

Answer:

b. 17%

Explanation:

Let's begin by stating that the human genome possesses around 3,000 millions of base pairs.

Therefore, if this retrotransposon is around 1,000 base pair and possesses 516,000 copies, it will produce 516,000,000 of base pairs overall.

Let's consider,

516 millions

--------------------- × 100

3000 millions

= 17.2% (approximately 17%)

it gives us a percentage of the human genome which is for this transposon.

Hemophilia is a hereditary bleeding disorder that primarily affects males. Why does this condition typically affect males more t
Ymorist [56]

Answer:

See the answer below

Explanation:

<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>

<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>

Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.

In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.
