When completing Punnett Squares, you cross the letters that meet up. For example, their are two TTs and two Tts. Dominant will always show before a recessive so if it's TT or Tt it will be the dominant version. two tt's mean that it's recessive. In a Punnett Square, one box = 25%.

Part A: The genotypic ratio is 50% TT and 50% Tt. The phenotypic ratio is 100% tall.

Part B: The two Tt's could produce a short plant because there is a 25% that the parents will both give t's.

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

               Mother:      Brown                                 Green

Father↓  

Brown                      Brown-Brown                 Brown-Green

Green                      Brown-Green                  Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%
