ANNEXES
factors that determined the success of the experiences of mendel:
1.1 the selection of the plants
For example, the pea has a simple crop growth at all times
1.2 The data record of each experience was thorough and precise:
This allowed recording the type of offspring in each generation and reach valid conclusions until today.
1.3 Selection of single characters:
It took one or two characters to better accuracy
1.4 The use of mathematics:
Especially in probability and combinatorial analysis to analyze their observations and formulate an explanatory hypothesis for each experiment
DA AS THE INHERITANCE OF SEX:
What determines a pair of sex chromosomes that are different in men and women.
In man there are 46 chromosomes. 44 are known as self-employed which are arranged in 22 pairs, the remaining two are known for being the sex chromosomes that determine sex. In
women are equal and is known as XX and in men are different, a chromosome is called X and another as Y.
In forming the gametes, the two chromosomes are divided so that half of the chromosomes sperm carrying X chromosomes and half the Y chromosome, instead of eggs carry an X chromosome
fertilization is done at random, that is, sperm can be made by one of two types.
When you have the chances that offspring are derived male or female, are equal, therefore being male or female is a mere chance.

INHERITANCE FACTOR RH
An individual is considered to be RH + has a component called agglutinogen, otherwise if you do not have is RH-
for scientific study has shown that the blood of black skin are 100% RH + while the white population is 85% RH + and is only 15% RH.
is important to know that the Rh + is dominant and obviously well-RH is recessive.

HUMAN GENETIC PROBLEMS 4.1
pathological characters arrived at
X chromosome The X chromosome may also carry some genes that will guide hereditary pathological characters in the new individual, such as hemophilia, color blindness, the Neopia and astigmatism. 4.1.1
Hemophilia: is an inherited disease that is defined by lack of blood clotting. Hemophilia is inherited as sex-linked character, who transmits the disease is the mother but not have it. Haemophilia men rarely have offspring.

4.1.2 Color blindness: is especially confusing colors red green and vice versa.

Myopia: is the eye's refractive reverse farsightedness in which the image is formed in front of the retina. Is an excess of power transparent media of the eye with respect to its length so that light rays from objects at some distance from the eye converge to a point before the retina.
Myopia is the most common visual problem in the world and it is a major eye ametropia.
Astigmatism: is an eye condition that usually comes from a problem in the curvature of the cornea, which prevents the clear focus of the objects that are close or distant.
In astigmatism, the magnitude of error of approach is different depending on the meridian axis of fixation, this makes the objects look distorted.
There are three types of astigmatism:
Simple: appears in one axis.
Composite: Same first, only now it is associated with myopia if the two main focus in front of the retina, or farsightedness if focus behind the two axes.
Mixed: When an axis focuses in front of the retina and one behind.
