Answer:
50%
Explanation:
Parent 1: TTYy ( Tall and yellow )
Parent 2: ttyy ( Short and green )
Probability of having tall offspring : TT X tt
= Tt : 100 % tall
Probability of having green offspring (yy) : Yy X yy =
Y y
y Yy yy
y Yy yy
= 50% or 1/2
Probability of having a tall, green offspring = 1* 1/2 = 1/2 or 50%
The odds that the offspring will be tall and have green peas is 50%.
An allele is a different form of the gene. Alleles represent the phenotype of the organism.
Given, (Y) yellow pea allele is dominant to the green pea allele (y).
Parent 1: TTYy (Tall and yellow)
Parent 2: ttyy (Short and green)
On crossing over:
TT x tt = Tt : 100 % tall
The probability of getting tall is 100%
On crossing over:
(yy) : Yy X yy =
Y y
y Yy yy
y Yy yy
The probability of having green offspring is 50% or 1/2
Thus, the probability of having a tall, green offspring is [tex]100\times \dfrac{1}{2} = 50\%[/tex]
