Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp
The correct answer is option D, Speciation
In the allopatric speciation, the geographical barriers such as mountains or rivers causes isolation of the population. The two population groups get completely separate from each other and thus develop different sexual preferences for mating.
The most likely answer is B, increased significantly. This is so, because of the vast amount of cars, and factories, still in use.So, based upon the statistics and the levels of pollution all over the world, I would have to answer B.
