\u201cspecial\u201d chromosome is present in the cells of the male individuals which
was called Y-chromosome<\/strong>. Since it proved that these two types of
chromosomes are connected with the determination of sex they were called
sexual chromosomes<\/strong>.
Wilson and Stevens have suggested a comparatively simple mechanism
of distribution of the sexual chromosomes in the process of cell division. They
have assumed that each egg and the half of the spermatozoa have an X-chromosome.
The other half the spermatozoa contains the Y- chromosome.
When the egg is fertilized by a spermatozoon with an X-chromosome a
zygote of two X-chromosomes (XX) is obtained which gives rise to an
individual of the female sex. When the fertilization is carried out by a
spermatozoon with a Y-chromosome then the zygote has the two types (XY)
and an individual of the male sex is developed from it (Fig. 2\u201314).<\/p>\n\n\n\n
