What is the difference between Sex linked recessive trait and Autosomal recessive or dominant trait??
Pls explain pointwise
Dear student,
Please find below the answer:
Autosomal linked recessive:
1) The trait is found on the autosomal chromosome but not on the sex chromosome.
2) There is no necessity that the diseased allele will show up every generation, i.e. they might skip a generation.
3) Either of the sexes can be affected in any generation. Example:- Cystic Fibrosis
Sex-linked recessive:
1) The trait will affect the sex chromosome but not the autosomal chromosome.
2) There is no necessity that the diseased allele will show up every generation, i.e. they might skip a generation.
3) Males are more often affected.
4) There are 50% chances for males to be affected and 50% chances for females to be a carrier of the disease showing allele.
Hope this information clears your doubt.
Regards.
