Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best describes how genes influence an organism’s traits?
A
Genes control the production of proteins, which affect the organism’s traits.
B
DNA controls the production of lipids, which determine the organism’s traits.
C
Carbohydrates control the production of genes, which affects the organism’s traits.
D
Genes control the development of sister centrioles, which determine the organism’s traits.
Explanation: 

Detailed explanation-1: -The expressed traits are a result of the specific genotypic combination of the alleles, which are a pair of genes . Also, a particular gene codes for a specific protein that determines the physical characteristics of an individual. This is how genes control the traits.

Detailed explanation-2: -Correct Option-B A specific length of DNA responsible for the inheritance and expression of the character. Explanation-Gene is a particular segment of DNA which is responsible for the inheritance and expression of a particular character.

Detailed explanation-3: -DNA ultimately determines the traits of an organism through gene expression.

Detailed explanation-4: -Traits can be determined by genes, environmental factors or by a combination of both. Traits can be qualitative (such as eye color) or quantitative (such as height or blood pressure).
