Location of Genes for Sex-Limited Traits
Genes of sex-limited traits are present on:
- Sex-chromosomes
- Autosomes — Correct Answer
- Both
- None of the above
Correct Answer: Autosomes
Genes of sex-limited traits are present on autosomes. These genes are present in both sexes but are expressed (phenotypically visible) only in one sex.
Sex-Limited Traits
| Trait | Sex Expressed In |
|---|---|
| Milk production | Female only |
| Egg production | Female only |
| Semen production | Male only |
| Secondary sexual characters | One sex predominantly |
The trait is limited to one sex due to the hormonal environment, not because the gene is absent in the other sex. A sire carries the gene for milk production but cannot express it.
