To determine:
Whether the notched ears in mouse are a Y-linked trait or a sex limited trait.
Introduction:
Some of the autosomal traits which appear only in one sex (male or female), are termed as sex limited traits. Genes responsible for these traits are present on autosomes, and not on sex chromosomes.
To determine:
The crosses which can be carried out to distinguish between Y-linked trait and a sex limited inheritance.
Introduction:
Sex linked traits are present on sex chromosomes and in inheritance all the progenies produced from affected parents will express the gene or carry the allele responsible for the trait. If the trait is sex limited, all the progenies produced from an affected parent will not necessarily express the trait as the traits are present on autosomes.
