Answer:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Explanation:
Note that the brown eyes is the dominant trait, denoted by B, while blue eyes is the recessive trait, denoted by b. In all cases of the Punnett square, if there is a dominant and recessive trait, the dominant trait will always come out on top.
The given Punnett square:
![\left[\begin{array}{ccc}&B&b\\B&BB&Bb\\b&Bb&bb\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26B%26b%5C%5CB%26BB%26Bb%5C%5Cb%26Bb%26bb%5Cend%7Barray%7D%5Cright%5D)
Note that there are 3 options (BB, Bb, Bb) respectively, in which there is the dominant trait B (brown eyes). Only in one case is there only the recessive trait b (blue eyes), or a 1/4 chance of obtaining blue eyes. Therefore, there is a 3/4 chance of obtaining a brown eye:
C. There is a 75% probability that an offspring will have brown eyes and a 25% probability that an offspring will have blue eyes.
Answer:
Branching diagram
Explanation:
Life is very diverse, yet all living things are related. Branching diagrams show how living things are related to each other.
From DNA to RNA, purines and pirimidines transform in this matter:
(A) adenine => (U) uracile ; because RNA has uracile instead of timine in DNA
(G) guanine => (C) citosine
mRNA: G U G C A C C U G A C U C C U G A G G A G
GUG-valine
CAC-histidine
CUG-leucine
ACU-threonine
CCU-proline
GAG-glutamic acid
GAG-glutamic acid

Answer:
Selective breeding
Explanation:
This method of breeding is particularly carried out by humans, breeders to produce desirable characteristics/traits in the offspring. They do this by crossing parents with these suitable characteristics to produce offspring that will inherit and possess these desirable traits.
