Examples of Sex-Limited Characters
Semen production, milk production and egg production are examples of:
- Sex-linked characters
- Sex-limited characters — Correct Answer
- Sex-influenced characters
- Autosomal dominant characters
Explanation:
Correct Answer: Sex-limited characters
Sex-limited traits: their genes are on autosomes, but expression is limited to one sex due to sex hormones. Milk production (females only), egg production (females only), and semen production (males only) are classic sex-limited traits.
Key Points about Sex-Limited Traits
- Gene is present in both sexes (on autosomes), but only expressed in one sex.
- Responsible for sexual dimorphism.
- Because sires cannot be directly selected for milk production (sex-limited), progeny testing is used for sire evaluation.
- Individual selection CANNOT be used for sex-limited traits.
