Mendel and Heredity
Mendel's experiments with garden peas led to our modern understanding of heredity.  British farmers had performed similiar breeding experiments with plants more than 200 years earlier, but Mendel was the first to develop rules that accurately predict patterns of heredity.  The patterns that he discovered form the basis of genetics.

Mendel's Rules of Heredity




















To cross-pollinate flowers of different colors, Mendel first removed the stamens - the pollen-producing structures - from one flower.  Mendel transferred pollen from a second flower to the pistil of the original flower.

Hemophilia

15_12-pedigree_hemophilia.jpg
Hemophilia has played an important role in Europe’s history, for it suddenly cropped up in the children of Great Britain’s Queen Victoria. It became known as the “Royal disease” because it spread to the royal families of Europe through Victoria’s descendants





hemophilia-1.gif
Hemophilia affects males much more frequently (1 in 10,000) than females (1 in 100,000,000). This occurs because a critical blood clotting gene is carried on the X chromosome. Since males only carry one X chromosome, if that is defective, hemophilia will immediately show up. An early death is likely. Females, on the other hand, carry two X chromosomes. If only one is defective, the other normal X chromosome can compensate. The woman will have normal blood clotting; she will simply be a carri er of the recessive defective gene. This fact will be discovered if some of her children are hemophiliacs. Naturally, women hemophiliacs are rare because it takes two defective X chromosomes in order for the condition to be seen.







Sex-linked Red/Green Color Blindness


XlinkRecessive.jpg
Color blindness is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. It is most commonly inherited from mutations on the X chromosome.





Albinism

About 1 in 17,000 human beings has some type of albinism, although up to 1 in 70 is a carrier of albinism genes.

Albinism results from inheritance of recessive alleles.  The condition is known to affect mammals (including humans), fish, birds, reptiles, and amphibians.  Albinism is characterized by a partial or total lack of melanin pigment in the eyes, skin, and hair.

ABO Bloodtyping - Genotypes



All humans and many other primates can be typed for the ABO blood group.  There are four principal types: A, B, AB, and O.  There are two antigens and two antibodies that are mostly responsible for the ABO types.  The specific combination of these four components determines an individual's type in most cases.
