Embryos can be male or female.
Either one.
If cells within a male embryo do not secrete testosterone at the proper time during development, the embryo will develop into a female despite being genetically male.
A Female ovum and a Male sperm fuse to create a zygote cell. It is the earliest developmental stage of the embryo.
In humans, gender is determined by the x and y chromosomes, with xx being a genetic female and xy being a genetic male
If a human egg (from the female) and a human sperm (from the male) join together, then the egg is fertilised by the sperm and a human embryo is created. This human embryo grows over 9 months into a baby.
No, an artificially implanted embryo can't grow inside a male. A male does not have the organs to sustain life.
If cells within a male embryo do not secrete testosterone at the proper time during development, the embryo will develop into a female despite being genetically male.

A Female ovum and a Male sperm fuse to create a zygote cell. It is the earliest developmental stage of the embryo.
An embryo, male or female, usually has two sex chromosomes, one from mom, one from dad. In a male's case, they would be XY. Rarely, nondisjunction occurs, and a child winds up XXX, XXY, XYY, or X. XXX and X become female, and XXY and XYY become male. So, it is theoretically possible for a male embryo to have three sex chromosomes.
In humans, gender is determined by the x and y chromosomes, with xx being a genetic female and xy being a genetic male
It's called asexual reproduction, when there is no male contribution, or there is no male-female differentiation. Parthenogenisis
The male gamete - spermatozoon and the female gamete - ovum.
If a human egg (from the female) and a human sperm (from the male) join together, then the egg is fertilised by the sperm and a human embryo is created. This human embryo grows over 9 months into a baby.
The X and Y sex chromosomes. If the embryo inherits an X and Y chromosome, it will be male. If the embryo inherits two X chromosomes, it will be female.

The male gametophyte in an angiosperm is the stamen. The female gametophyte in an angiosperm is the pistil.This is completely wrong. The male gametophyte consists of the generative cell and the tube cell in the pollen grain. The female gametophyte is the 7-celled 8 nucleate embryo sac.
