All embryos appear female during early development. <br> a. True<br> b. False
guapka [62]

Answer:

True

Explanation:

Geneticists have discovered that all human embryos start life as females. In the early development in the embryonic stage, this is true both for humans and mammals. This changes only at the 2nd month (in the case of humans, since different mammals have different gestating periods) if the embryo can elaborate enough androgens (dominant male hormone) to offset the maternal estrogens (dominant female hormone) then, maleness develops.
