Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Co-Dominance and Incomplete Dominance both have
A
2 dominant traits
B
2 recessive traits
C
1 dominant trait
D
1 recessive trait
Explanation: 

Detailed explanation-1: -Incomplete dominance and codominance are both types of inheritance where one allele (a form of a gene) isn’t completely dominant over the other allele. This results in a new phenotype (the physical characteristics of an individual).

Detailed explanation-2: -Codominance That is, instead of one trait being dominant over the other, both traits appear, such as in a plant or animal that has more than one pigment color.

Detailed explanation-3: -As mentioned earlier, incomplete dominance is a partial dominance, meaning the phenotype is in between the genotype dominant and recessive alleles. In the above example, the resulting offspring has a pink color trait despite the dominant red color and white color trait due to incomplete dominance.

Detailed explanation-4: -The similarities between codominance and incomplete dominance are listed below: Both codominance and incomplete dominance are dominant in nature. Mendelian inheritance laws cannot explain the patterns of inheritance. An allelic or intragenic gene interaction causes codominance and incomplete dominance.
