The genotype of the parents is Ff and Ff.
Explanation:
Data given:
freckles = dominant, FF or Ff genotype
no freckles = recessive, ff
genotype of parents with freckles = ?
child has no freckles = ?
The possibility of the child having no freckles is because the parent could be heterozygous dominant for the trait i.e freckles.
The genotype is Ff X Ff
F f
F FF Ff
f Ff ff
It can be seen from the Punnet square that there are 25% chance of the child to be with no freckles when both parents are having freckles.
The genotype ratio is 1:2:1
The phenotype ratio is 3:1
3 with freckles and 1 with no freckles.
