To determine the genotype ratio from the given genotypes (fF, fF, ff, ff), we first count each genotype. There are 2 fF and 2 ff. The genotype ratio can be expressed as 2 fF : 2 ff, which simplifies to 1 fF : 1 ff. Thus, the genotype ratio is 1:1.
The offspring from an FF X ff cross will all have the genotype Ff.This is because they receive one allele from each parent, and in this case they can only receive an F from the FF parent and an f from the ff parent.

To determine the probability of an offspring mouse being born with the genotype ff ee, you need to know the genotypes of the parent mice. If both parents are heterozygous (Ff Ee), the probability of producing ff offspring is 1/4 and for ee offspring is also 1/4. To find the probability of the combined genotype ff ee, you multiply these probabilities: (1/4) x (1/4) = 1/16. Thus, there is a 1/16 probability that an offspring mouse will have the genotype ff ee, assuming both parents are Ff Ee.

Child's genotype would be homozygous recessive alleles (nn) and parents would both have heterozygous dominant alleles (Nn).
Yes, a genotype of TT or ff indicates a purebred individual for a specific trait. TT signifies homozygous dominant, while ff signifies homozygous recessive.
Mm, Ff, Gg, Ll, Ss and ect
If all of the children have freckles, that means that both parents had dominant genotypes. (Mother; FF and Father; FF). Or, one parent could have a hybrid genotype. (For example, Mother; Ff and Father; FF). Based on the outcome of a Punnett Square, either one parent must have a hybrid and the other dominant, or both must have dominant genotypes.

ff
The genotype ff represents a homozygous recessive individual for a specific gene. This means that both alleles for the gene are the same and both are the recessive allele (f). This individual will exhibit the trait associated with the recessive allele.
