What is the phenotype ratio of offspring to be expected from the CceE X cce cross?
| June 25, 2021 | education
To find the ratio of phenotypes and genotypes in offspring, it is necessary to draw up a cross-breeding scheme for these individuals, describing what gametes are formed in the parents and what combinations are possible in the offspring.
Crossing scheme:
Parents: СсЕЕ х ссее,
Gametes: CE, cE x se,
Offspring: СсЕe, ссЕe.
There are only 2 genotypes and 2 phenotypes, because in the first case, both dominant traits will appear (or intermediate in case of incomplete dominance), in the second, one recessive will appear.
The phenotype ratio is 1: 1.
