PHENOTYPE: 75% with freckles 25% without freckles GENOTYPE: 1FF:2Ff:1ff
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.
Dd is the heterozygous genotype for dimples.
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.
The man's genotype is CcFf. The woman's genotype is CcFf. These genotypes only apply if curly hair is dominant to straight hair. Freckles is dominant to no freckles. Also if a man who is heterozygous for both curly hair and freckles who then marries a woman with the same genotype.
Yy is a heterozygous genotype. Homozygous would be YY or yy.
A heterozygous genotype
One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.
A Heterozygous genotype means an organism that has both the dominant and the recessive gene.
The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.
The heterozygous genotype
A heterozygous genotype, is the genetic makeup of different alleles.
