Alentil plant with spotted seeds was crossed with another that had dotted seeds. the f1 plants turned out to have seeds that had spots and dots. what could be the reason?

a: lentil seed pattern is affected by codominance.

b: lentil seed pattern is affected by incomplete dominince

c: lentil seed pattern is affected by complete dominance.

The answer is a:lentil seed pattern is affected by codominance.

Codominance is a form of inheritance in which two different alleles of a gene are both expressed.
In this example, one allele of the gene is responsible for dotted seeds and the other is responsible for spotted seed. If both these traits appear in heterozygous plants, then it is codominance. Let's take for example flowers - after crossing red flower plant with white flower plant, heterozygote offspring would red purple-white flowers, which means it express both traits and it is codominance.

This is not complete dominance because in this case, heterozygote would express a dominant trait (in the example of red and white flowers, heterozygote will be with red flowers). This is not incomplete dominance as well, because in that case, the heterozygote would have some intermediate trait (in the example of red and white flowers, heterozygote will be with pink flowers which is intermediate color between red and white).

Ur very welcome for
