miss Akunina [59]

Answer:

The allele frequencies of both populations are likely to be similar.

Explanation:

An allele is a variant form of a given gene. Sometimes different alleles can cause variations in the observable characteristics of the species examined.

In the option given the chance that alleles are similar is very high because both populations exchange migrants very frequently and at a high rate so the genes of both populations are mixed very often.

I hope this answer helps you.

For a species with a haploid number of 15 chromosomes, how many different combinations of maternal and paternal chromosomes are
babymother [125]
The answer is:  " 32,768 " .
___________________________________________
Explanation:
__________________________________________________________
 →  2ⁿ  = ? ;  {that is: "2" , raised to the "n th" power, equals {<u>what value</u>} ?
___________________________________________
 → Note that "n" is the haploid number, which is: 
                           "15" (value given within this very question).
__________________________________________________
→ So we plug in "15" for "n" ; to obtain the "final value" —
                                                          which is the answer.
__________________________________________________
           →  As such:  " 2¹⁵ = 32,768 " .  (using scientific calculator online).
___________________________________________________
           →  The answer is:  " 32,768 " .

Please help meeeeeeeeeeeeeeeeeeeeeeeeeee
Dmitry [639]

Answer:

1.) The two gametes found in humans are the sperm and the ova.

2.) Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).

3.) Because the alleles that the mother and the father carry are mixed together in the offspring.

4.) Because it only introduces genetic variation into the population if a random mutation in the organism's DNA is passed on to the offspring.

Please this is all I can answer
