Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How many alleles (letters) does a child get from EACH parent for each trait (For example, a father provides how many of his alleles for eye color)?
A
1
B
2
C
3
D
4
Explanation: 

Detailed explanation-1: -The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways.

Detailed explanation-2: -An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.

Detailed explanation-3: -A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. We represent these gene pairs by writing a combination of two letters.

Detailed explanation-4: -One allele for every gene in an organism is inherited from each of that organism’s parents. In some cases, both parents provide the same allele of a given gene, and the offspring is referred to as homozygous ("homo” meaning “same") for that allele.
