The comparison of the genotypic and phenotypic ratios of the crosses are as follows:
50% DD, 50% Dd (genotype); 100% Dominant
100% Dd (genotype); 100% dominant
50% Dd, 25% DD, 25% dd (genotype); 75% dominant, 25% recessive (phenotype)
50% Dd, 50% dd (genotype); 50% dominant, 50% recessive (phenotype)
<h3>How to find genotypic and phenotypic ratios?</h3>
In genetics, the genotype is the genetic constituent of an organism while the phenotype is the expressed trait.
According to this question, the genotypic and phenotypic ratios of cross combinations involving two alleles D and d is given.
The genotype of the offsprings of each cross is as follows:
- DD x Dd: DD, DD, Dd, Dd
- DD x dd: Dd, Dd, Dd, Dd
- Dd x Dd: DD, Dd, Dd, dd
- Dd x dd: Dd, Dd, dd, dd
Therefore, the genotypic and phenotypic ratios of these crosses are as follows:
50% DD, 50% Dd (genotype); 100% Dominant
100% Dd (genotype); 100% dominant
50% Dd, 25% DD, 25% dd (genotype); 75% dominant, 25% recessive (phenotype)
50% Dd, 50% dd (genotype); 50% dominant, 50% recessive (phenotype)
