A trait determined by a gene on the Y chromosome is transmitted
Correct answer: D. to daughters only
- A. from mother to sons
- B. from father to all his sons
- C. equally to sons and daughters
- D. to daughters only
Explanation
Only males carry a Y chromosome, and a father passes it to every son and no daughter, so Y linked traits run strictly down the male line. Nothing on the Y can ever appear in a female.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
