Answer:

They are formed from different eggs and sperms.

Explanation:

Fraternal twins appear different a lot of times because they are formed from different eggs and sperms.

<em>Two eggs that are different in their genetic make ups get fertilized by two different sperms which are also different genetically. Hence, two zygotes with different genotypic and phenotypic characteristics results. </em>

This is as opposed to twins that look alike which are formed from the same egg and sperm. A single egg gets fertilized and then divides into two mitotically to give rise to two eggs with the same genetic make up and physical characteristics.

neonofarm [45]
The answer is letter C.) <span>Affected father and carrier mother 

"Affected" refers to the person having the recessive gene of the color blindness, while "carrier" means the person carries two of the recessive genes of the trait. For the couple to produce a 1:1 ratio of normal to color-blind offspring, they would need to have the combination of affected father and carrier mother.
