Colt1911 [192]

Answer:

Frequency of BBBB genotype = 0.68

Frequency of BBBG genotype = 0.2

Frequency of BGBG genotype = 0.12

Explanation:

Genotype frequency = number of individuals of that genotype/ total number of individuals

In this population three types of individuals are present: blue, turquoise and green.

Frequency of BBBB genotype (blue) = 170/ ( 170 + 50 + 30)

= 170/250

= 0.68

Frequency of BBBG genotype (turquoise) = 50/250

= 0.2

Frequency of BGBG genotype (green) = 30/250

Has the question of the origin of the universe been solved? yes, we now know the Universe was exploded and expanded into existen
dalvyx [7]
No, although there are several theories with increasing evidence, there is still no way to know for sure how it occurred. The great mystery of the beginning of universe is way too vast and vague. Theories can only be proven by presenting a solid proof, but great creations such as universe itself doesn't have to be solved. Various possibilities must have happened or there must be a one conclusion leading to its existence; but moreover, it is not our problem to solve. The confirmation of beginning of its existence will only feed the curiosity of humans.
