The Human Female has 22 pairs of chromosomes plus a pair of 2 "X" sex chromosomes for a total of 23 pairs of chromosomes.
The Human Male has the same 22 pairs of chromosomes, plus 1 X sex chromosome and 1 Y sex chromosome.
Lutino cockatiels are a colour not a gender. However, it does happen that because of the genetics and chromosones they are most often female although there are some males lutinos around (or there wouldn't be any left.)
123 chromosomes
The female can only pass on ONE "X". an XX female offspring must get the second X from the father.
They are called chromosones
76 Chromosones.
A molar pregnancy is an abnormally fertilized egg. Molar pregnancies occur when the fertilized egg does not have any of the mother's chromosones, or the father's chromosones duplicate.
When the process meiosis creates new gametes (sex cells), each gamete has haploid, or n chromosones (half the number of other cells), which means that each gamete has 23 chromosones. Chromosones come in pairs, and when meiosis occurs it randomly picks one chromosone from each pair, which is what causes variation. We inherit 23 chromosones from each parent as well, so that adds to the variation even more. Chromosones and alleles are both found in the same place. Hope that was what you were looking for.
When a horse and a human mate and their chromosones thingys match.
23 chromosones

Chromosones become visible during prophase.
because their body chromosones require their body mass to stop at this age. males are taller because of their xy chromosones and therefore are taller but body mass still blocks at 18.
