Genetic Inheritance
Humans have two sets of chromosome,when parents conceive they each contribute one set of chromosome
Most of the cells in our bodies contain two sets of chromosome (2*23) but the egg and the sperm cell contain one set of chromosome.DNA is present in each of our cells.It contains all of the information that makes us humans.
Everyone has two copies of every gene,one inherited from the mother and one inherited from the father.
These individual copies of the gene referred to as alleles.
What is X-linked inheritance?
The two sex chromosome (the X chromosome and the Y chromosome) are responsible of detecting
if it is a men or women
Women have two x chromosomes while men have one x chromosome and one y chromosome.
women have two copies of every gene since they have two X chromosomes, men have only one copy of the genes on their X chromosome, since their other sex chromosome is a Y chromosome and it carries a set of the specific male genes.
What is Dominant Inheritance?
A dominantly inherited disease is one in which a single defective copy of a gene can cause disease.
In order for a couple to have an affected child, both the couple most likely have the disease themselves
