7 0

The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

At what level does gene variability quantify genetic variation?

sergejj [24]

Answer:

Answer is whole-gene or whole-genome.

Explanation:

Genetic variation explains that, no matter how related or identical some organisms might be, there is a or some characters that make them different from one another. These difference is referred to as variation.

Furthermore, whole-gene means the coding and non-coding regions of the DNA>

There are some activities or occurrences that cause genetic variation, these are gene flow, mutation and sexual reproduction.

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.
