2.  In humans genes that determine sex are
in a pair of chromosomes (gnomosomes),
the other 22 pair are called autosomes.
 Males have 22 pairs of autosomes and XY
chromosomes, while females have 22
pairs of autosomes and XX
chromosomes.

3.  Supposing the case of a gene not determining a sex
characteristic. However this gene is located on the X
chromosome. The case of this chromosome it’s said to
be sex linked ( this make Hemophilia and color
blindness )
 In this case, it can only be transmitted from father to
son.

4.  We consider a rare disease, one that have
low incidance in the population, it isn´t
very common.

5.  ALD is a genetic disease due to a X-link gene
manifestation.
 It’s due to a abnormal accumulation of fats in the
central nervous system and it causes the loss of myelin
surrounding the axon of important neurons.
 The signs and symptoms are: Ataxia, abnormal
behaviour, seizures, dementia… it conclude with dead.
 The probability of having a child with ALD 25%.

6. It propagates electrical impulses along neurons.

7.  Fatty acids: Long chains of Hydrocarbons
 Fatty acid chains with single bonds
between the carbon atoms surrounded
by hydrogen atoms are termed saturated,
but if there are double bond between
them, the chain is termed unsaturated.

8.  One single bond: monounsaturated
 Two or more bonds: polyunsaturated
 Saturated fats are present in oil, meat…
 Monounsaturated fats are present in
sunflower oil…
 Polyunsaturated fats are present in oily
fish…

9.  It’s an X-linked recessive disease.
 Itreduces bloods clot formation in
trauma and heavy bleeding. Female
carriers it.

11.  Itoccurs when males have 47
chromosomes( XXY)
 Lack of hair
 Increase od breast tissue(Gynecomastia)
 Undeveloped testes(Hypogonadism)
 Lacking of sexual
differentiation(Eunuchoid)
