Sexual reproduction is important for the survival of the species. It is important for ALL BUT ONE of these reasons. That is
Ne4ueva [31]

Answer:

C) it is necessary for the survival of the individual.

Explanation:

Sexual reproduction is rarely, if ever, necessary for the individual. This is not a reason for its importance. However, while not important for the individual, sexual reproduction is important for the species. It allows genetic variability among offspring, as well as mutations. This ensures that not all members of a species are the same, and in this way, they have a better chance of surviving. Moreover, it allows for offspring to be produced at a faster rate.

HURRY PLEASE I NEED A PARAGRAPH. Describe how cell membranes are selectively permeable.
Simora [160]

Explanation:

Cell membranes are selectively permeable. Some solutes cross the membrane freely, some cross with assistance, and others do not cross at all.

Male-patterned baldness is more common in males as the name suggest.why is this?
Ray Of Light [21]

Answer:

mark brainliest :))

Explanation:

Because baldness is a sex-linked trait.  

In other words, men are simply more likely to express the trait for baldness than women are, because they only need one set of genes for baldness, while women need two.  

If, for example, for each gene there is a 1/2 chance that the gene will be for baldness and 1/2 that it will not, then men have a 1/2 chance (because 1/2^1 = 1/2) of being bald, while women have a 1/4 chance (because 1/2^2 = 1/4) of being bald.  

This is the reason it's called "male-pattern baldness": it is more common in males. However, this does not explain nor rule out the dearth of women with baldness-women can get it too: it's just less common

skad [1K]

Answer:

25% colorblind daughter: 25% colorblind son: 25% carrier daughters with normal vision: 25% normal son.

Explanation:

The genotype of a color-blind man is X^cY and the genotype of the heterozygous carrier female is X^cX. A cross between X^cY and X^cX would produce a progeny in following ratio=  

25% colorblind daughter: 25% colorblind son: 25% carrier daughters with normal vision: 25% normal son.

Therefore, the couple is likely to have 50% normal son and 50% affected son. Likewise, the couple is likely to have 50% normal daughters and 50% colorblind daughters.
