The events that lead to genetic drift are _______. a. always natural disastersb. random
c. predictable
d. related to human activities

Answers

Answer 1
Answer: I think the correct answer from the choices listed above is option B. The events that lead to genetic drift are random. Genetic drift involves the change in relative frequencies of different genotypes in a small population which happens by chance so they are unpredictable.
Answer 2
Answer:

The events that lead to genetic drift are random. Genetic drift is a random change in the allele frequencies of a population. It is caused by chance events, such as the founder effect or the bottleneck effect. Hence option B is correct.

These events can cause some alleles to become more common in a population, while other alleles become less common.

Genetic drift is not always caused by natural disasters. It can also be caused by human activities, such as migration or selective breeding. However, the events that lead to genetic drift are always random.

Therefore, option B) Random is correct.

Hemophilia is a sex–linked disorder that is caused by a defective gene on the X chromosome. What will be the pattern of inheritance of the offspring of a hemophiliac father? A. The father passes the gene to all his sons but to none of his daughters. B. The father passes the gene to all his daughters but to none of his sons. C. The father passes the gene to all his daughters and all his sons.

Answers

"The father passes the gene to all his daughters but to none of his sons" is the one among the following that will be the pattern of inheritance of the offspring of a hemophiliac father. The correct option among all the options that are given in the question is the second option or option "B". I hope it helps you.

Answer:

Option (C).

Explanation:

Sex linked disorder may be defined as the disorders that are caused by the mutation or defects in the sex chromosome. Two main types of sex linked disorder are sex linked recessive and sex linked dominant.

Hemophilia is caused due to the defect in the clotting factor. This is a sex linked recessive disorder that are transferred from female to their sons. The hemophilic father has only one X chromosome and they will transfer this affected X chromosome to their daughters and none of their sons. Since, sons receive Y chromosome from their father.  

Thus, the correct answer is option (C).

Among a species of butterflies, the color blue b. is a dominant trait. Yellow color
b. is a recessive trait. If a pure blue butterfly (BB) mates with a pure yellow (bb), what will the offspring look like?

Answers

Answer:

100% of the offspring are blue butterflies.

Explanation:

B is a dominant allele, determining the blue color of a butterfly.

b is a recessive allele. This means a bird with bb genotype is yellow in color.

A pure blue butterfly (BB) produces only B gametes, and a pure yellow butterfly (bb) gives onl b gametes.

Therefore, the offspring in the BB x bb cross are all blue in color.

Answer:

its a

Explanation:

its all blue butterflies (:
