Differences in blood flow during embryo development mean that identical twins (i. e. monozygotic) will develop different a. Eye colors

b. Fingerprints c

. Blood types d.

Sexes

e. Hair colours

I can't seem to find a definite answer online, does anyone know what this is?

The answer is D(sexes)

Explanation:

This is because monozygotic twins are genetically nearly identical and they are always the same sex unless there has been a mutation during development.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
