Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Eye color is a trait that two parents could pass on to their children even though the trait might not be expressed in the parents. Such a trait is considered to be
A
acquired
B
inherited
C
neutral
D
positive
E
negative
Explanation: 

Detailed explanation-1: -Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms.

Detailed explanation-2: -Eye color inheritance pattern A child’s eye color depends on the pairing of genes passed on from each parent, which is thought to involve at least three gene pairs. The two main gene pairs geneticists have focused on are EYCL1 (also called the gey gene) and EYCL3 (also called the bey2 gene).

Detailed explanation-3: -Heredity, which is also known as inheritance or biological inheritance, is the passing of traits from parents to their offspring.

Detailed explanation-4: -Eye color is an example of incomplete dominance. According to this law of dominance, hybrid offspring will only inherit dominant traits in phenotype. Such alleles which are suppressed are called the recessive traits while alleles that determine the trait are known as dominant traits.
