Let F represent freckles and f represents no freckles
Mother is heterozygous, that is, Ff
And her phenotype is freckled
This tells us that F is dominant allele
Therefore is recessive
Father doesn't have freckles, his chromosomes are ff
Possible progenies :
Ff, ff, ff, Ff
Since the child doesn't have freckles, he has the recessive alleles
That means he is homozygous recessive (option 2)
Mother is heterozygous, that is, Ff
And her phenotype is freckled
This tells us that F is dominant allele
Therefore is recessive
Father doesn't have freckles, his chromosomes are ff
Possible progenies :
Ff, ff, ff, Ff
