How baby's are made
-
Meiosis
it goes through 2 cycles
-
-
-
telophase 1: the cell separates into 2, with 2 copies of half of the genetic information compared to the original cell
The next cycle of PMAT is very similar to mitosis where the sister chromatids split, it ends in 4 cells each having 1 copy of half the genetic information.
-
Meiosis in women: creates 1 egg cell in the ovaries, the rest being polar bodies. This happens because that one cell needs all the mechanics to grow a human
-
Fertilization happens when an egg cell and a sperm cell come together, which gives the fetus 46 chromosomes.
karyotypes
-
Males have XY chromosomes and females have XX, the Y chromosomes are usually much smaller than X
There can be extra chromosomes added, like trisomy 21 which causes down syndrome.
