Answer:
a) Ratio of homozygous to heterozygous offspring 1:1
b) Percentage of the offspring that are homozygous recessive 50%
Explanation:
When parents with genotype "Tt" and "tt" are crossed , the following offsprings are produced -
T t
t Tt tt
t Tt tt
The hetrozygous offsprings produced in this cross is Tt
The homozygous offsprings produced in this cross is tt
So, the total number of hetrozygous offsprings = 2
The total number of homozygous offsprings = 2
a)
Ratio of homozygous to heterozygous offspring
[tex]\frac{2}{2} = \frac{1}{1} \\[/tex]
b)
Percentage of the offspring that are homozygous recessive
[tex]\frac{2}{4}*100\\= 50[/tex]%
