Answer: The correct answer is-
The percentage of the offspring that are expected to be homozygous recessive (qq) is 0 %.
As per the information given in the question, the genotypes of parent are-
Homozygous dominant ( QQ) and a heterozygous ( Qq).
Gametes produced are- QQ parent will produce Q and Q gametes while Qq will produce Q ands q allele.
A dominant allele ( represented by capital letter such as Q) always masks the expression of recessive allele ( represented by small letter such as q)
Homozygous genotye has same alleles whereas heterozygous genotype contains different alleles ( one dominant and one recessive such as Qq).
When the parents are crossed, they will produce 50 % QQ and 50% Qq offsrping but no qq offspring will be produced
