A person who is homozygous for the X chromosome is female.
Women have two X chromosomes, which means they are homozygous for the X chromosome - the word homozygous means that they have 'two chromosomes of the same kind.' Men have different types of chromosomes - XY.
The human genome density ranges between 12-15 genes per Megabase pairs. This is because humans have approximately 2000 genes in a total of approximately 3 billion base pairs. However, some primitive organisms have an even larger gene density
than humans. An example is bacteria with gene densities ranging between 100 –
500 genes/Mb. Gene density is therefore
not a good characteristic in determining
the complexity of an organism.
From diffusion of nutrients from underlying layers
The nucleus of an atom contain protons and neutrons, which make up most of the mass of an atom.
