Sex Linked
Sex linked character and
observable feature of an organism control by the genes on the chromosome that
determine the chromosome of both male and female . This linked inheritance is
straight carried in either the X or the Y-chromosome is more likely to be
express in male as they have only one X-chromosome .
The presents of two X-chromosome
in female can suppress expression when one of them the genes for strait &
the other doesn’t. X- linked trait fold and many categories like- recessive , dominant
& co-dominant which influence their expression in member of both the sexes. A trait due to a gene in the
Y-chromosome will only show it male & not in female .
Ex. Of ex linked trait is colour
blindness , Haemophilia , hairy ear.
Sex limited trait : Sex limited genes are
gene which are present in male & female both sexes probably in the autosome. But are normally express
only in the gender having the appropriate hormonal determiner. The genes for
the trait can be carried & transmitted by the opposite sex although it is
not displayed in that sex be of anatomical & physiological different.
Ex. Of beard in males, Milk
secretion in female are generally sex limited trait.
# Sex influence trait
:- These
are autosomal trait. That are influence by sex. The character seems to at as a dominant in one
sex & they recessive in the other.
Sex control character also called sex influence character .
A genetically control feature
that may appear in organism in both sexes but it express to a different degree
in each. The character seems to at as dominant one sex & the recessive in
the other .
