The trait present in both sexes but more common in one sex is:
Correct answer: D. Sex influenced
- A. X-linked
- B. Y-linked
- C. Sex limited
- D. Sex influenced
Explanation
Sex-influenced traits are autosomal traits that are influenced by sex. If a male has one recessive allele, he will show that trait, but it will take two recessive for the female to show that same trait. One such gene is baldness. A lot of sex-limtied traits can determine parental carriers by using a pedigree.

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.
