A marriage between normal visioned man and colour blind woman will produce offspring:
Correct answer: D. Colour blind sons and carrier daughters
- A. Colour blind sons and 50% carrier daughter
- B. 50% colourblind sons and 50% carrier daughter
- C. Normal males and carrier daughters
- D. Colour blind sons and carrier daughters
Explanation
In the standard Mendelian pattern, a marriage between a normal-visioned man and a color-blind woman results in sons with normal vision and daughters who are carriers of color blindness. If the question context or genetics in the scenario indicates a different pattern, it would represent an a typical or non-standard genetic situation.

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.
