Pattern baldness, moustaches and beard in human males are examples of:
Correct answer: C. Sex influenced traits
- A. Sex linked traits
- B. Sex limited traits
- C. Sex influenced traits
- D. Sex determining traits
Explanation
Sex-linked traits are located on the sex chromosomes and are inherited differently in males and females. Sex-limited traits are expressed exclusively in one sex and not the other. Sex-influenced traits are influenced by the sex of the individual and can be expressed in both sexes, with differences in expression often due to hormonal or genetic factors. Sex-determining traits determine an individual's biological sex based on the presence or absence of specific sex chromosomes. In the context of your question, pattern baldness, mustaches, and beards in human males are examples of "c. Sex-influenced traits" because they are influenced by sex hormones and can be expressed in both males and females but tend to be more prominent in males due to hormonal factors.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
