WILL MARK BRAINLIEST! Can someone help me wit dis "question"? When two different sperm fertilize two eggs,

a.) fraternal twins result.
b.) identical twins result.
c.) twins of different sexes always result.
d.) twins of the same sex always result.

When two different sperm fertilize two eggs, fraternal twins result (option a).

Explanation:

Fraternal twins are the result of the separate fertilization of two maternal eggs by two paternal sperm, with the obtention of two zygotes with different DNA.

Although the embryonic development of fraternal twins occurs at the same time in the maternal uterus, each embryo will have an individual placenta and embryonic sac, with different development and characteristics, sometimes including sex.

The other options are not correct because:

    b. Identical twins come from the division of the zygote after fertilization, obtaining siblings with the same DNA and who share the same placenta and embryonic sac.

    c. Twins of a different sex do not always occur.

    d. Same sex twins always occur when they are identical twins.

precisely the author keeps the interest of readers not describing clearly the   kind of relationship in giselle's family. by doing this, readers had to imagine and assume how it was.   instead, the author described better scenes with dark star and the influence of books about horses in giselle's life and actions.   also the fact that she broke her arm but not referring to it in detail leads the readers to imagine and guess what could have occurred.
