Question
In a rare pea plant species the length of the stem is the result of the expression of the gene “T”, the allele “T” codes for long stems while the allele “t” codes for short stems. In this same species the gene “G” code for the color of the seeds, the allele “G” codes for green and the allele “g” codes for brown.1-What are the genotypes of a filial generation when the genotypes of their parents are TTGG and TtGg? Report the result in percentages.
2-What are the phenotypes of the filial generation above? Report the result in percentages.
3-According to the genotypes of the filial generation and the gene sequences provided below determine the sequences of the proteins made by plants of this filial generation and report the percentages of plants that express each protein.
The sequences of the antisense strands of the different alleles for genes “T” and “G” are listed below.
T: AACTCTGTATGCTACCCCTAATGTTCGCACGGGACATTTG…
t: AACTCTGTATGATGATGCTACCCCTATTCGCACGGGACAT…
G:AATTAACCGGATGATGGCCATGGGCCGGCCGGATGG…
g:AATTAACTGGATGCGCGCGCGCCCCCGCGCGCGCGC…
if i can get atleast question 3 right i will be thankful thanks
