<h2><u>Full Question:</u></h2>
Which of the following would result in fraternal twins, who don't have identical DNA? A. Two sperm fertilizing a single egg B. One sperm fertilizing a single egg C. Two sperm fertilizing two different eggs that were released in the same cycle D. One sperm fertilizing a single egg that splits into two embryos
<h2><u>Answer</u>: </h2>
Fraternal twins do develop when two sperms do fertilize two different ova that are released at the same time of a menstrual cycle.
Option C
<h3><u>Explanation:</u></h3>
Twins are of two types - Monozygotic twins or identical twins, and Dizygotic twins or fraternal twins.
Fraternal twins develop rarely, when during the menstrual cycle of the would be mother, two ova are released by two ovaries. So, two sperms fertilize the two ova separately. These zygotes develop into two separate embryo in their own separate amniotic sac. Being developed from separate sperm and separate ovum, the twins have not much similar characteristics unlike identical twins.
Only the fraternal twins can have different genders, like one can be male and other female. Monozygotic twins are always of same gender.
The parents of the Colts are so genetically similar that the Colts would suffer from various birth defects.
