Heredity is the passing of traits from parents to offspring. Through either sexual or asexual reproduction. This is when a offspring cell acquires predisposed to the characteristics of its parents cells. Also through heredity species evolve through the natural selection of specific traits.

Gregor Mendel was a German speaking scientist from Augustinian who gained posthumous fame as the founder of modern scientific genetics. Though farmers knew of cross breeding of animals for centuries, Mendel's pea experiment established many rules for heredity. He noticed the small peas never grew and the big peas always stayed tall but that wasn't always the case.

An allele is one of a number of alternative forms of the same gene or genetic locus, sometimes different alleles can result in different observable pigmentation.

A Dominant trait is a relationship between alleles of one gene, in which the effect on phenotype of one allele masks the contribution of a second allele at the same locus.

A Recessive trait is an allele that causes a phenotype that is only seen in a homozygous genotype and never in a heterozygous genotype.

Incomplete Dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele.

Homozygous and Heterozygous Alleles are Alternative forms of a given gene are called alleles, and they can be dominant or recessive. When an individual has two of the same allele, whether dominant or recessive, they are homozygous.

Reginald Punnett and the Punnett square The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment and Reginald Punnett is Reginald Punnett FRS was a British geneticist who co-founded, with William Bateson, the Journal of Genetics in 1910.

A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next, most commonly humans, show dogs, and race horses. It is used Determine if the pedigree chart shows an autosomal or X- linked disease if it is a 50/50 ratio between men and women the disorder is autosomal.

It looks like the blood is all swollen from the inside and makes the skin all bruised.
Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern. The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes. In males, one altered copy of the gene in each cell is sufficient to cause the condition.
