Answer:

The two original species will eventually fuse into a third new species, and disappear.

Explanation:

According to Darwin's theory of evolution, species that are better adapted to their environment have greater chances of surviving long enough to reproduce and pass on these favourable characteristics to their offspring. This is known as 'survival of the fittest'.

The original species lack the resilience of the new hybrid species hence the two original species will eventually disappear and fuse into the third specie.

Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
