We'llsay F is dominant for freckles and f is recessive for non-freckled.
The father is ff
The mother is Ff
The child is ff.
Probability of this cross producing a homozygous recessive child is 50%.
There isn't a precise term for this cross.
Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
Yes, freckles are a physical trait that can be determined by genetic factors. The development of freckles is influenced by a combination of genetic predisposition and exposure to sunlight, rather than being solely determined by a single recessive gene.
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.
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
Freckles are not controlled by a single dominant gene. They are influenced by multiple genetic and environmental factors, making their inheritance complex and not solely based on dominant/recessive patterns.

Yes, freckles are a physical trait that can be determined by genetic factors. The development of freckles is influenced by a combination of genetic predisposition and exposure to sunlight, rather than being solely determined by a single recessive gene.
PHENOTYPE: 75% with freckles 25% without freckles GENOTYPE: 1FF:2Ff:1ff
There is a 75% chance that their children will have freckles and a 25% chance that their children will not have freckles. This is because both parents are carriers of the freckles allele and can pass it on to their offspring.
Yes, if they both carry a recessive (hidden gene) for freckles, then yes their child would have a 25% chance of having freckles.

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.
Freckles are not determined by a single recessive gene. They are the result of a combination of genetics, particularly the presence of certain variations in the MC1R gene, and exposure to sunlight. The inheritance of freckles can vary depending on the specific genetic traits passed down from parents.
Freckles are considered a dominant trait, as they are caused by a dominant allele. This means that individuals only need to inherit one copy of the allele from either parent in order to have freckles.
