Question

7. If the phenotypic ratio in the F2 generation is 3:1, what kind of cross was made? What is the mode of inheritance? 8. If the phenotypic ratio in the F2 generation is 9:3:3:1, what kind of cross was made? What is the mode of inheritance? 9. Using Mendel's experimental design, what would be the expected phenotypic ratio in the F2 generation of a monohybrid cross for flower color, where incomplete dominance is the mode of inheritance 10. Phenotypic ratios and genotypic ratios are always depicted as ratios of small whole numbers, 3:1, 1:2:1, 9:3:3:1. What would be the expected phenotypic ratio in the F2 generation of a monohybrid cross using Mendel's experimental design if you produced 10,000 progeny? Why?

Explanation / Answer

7. This ratio is monohybrid cross result. In monohybrid, one character is cross at a specific time. This inheritance is called as dominance inheritance. Also known as Mendel inheritance.

8. This ratio is dihybrid cross results. In dihybrid, two characters are crossed at a specific time. This inheritance is called as dominance inheritance  

9. According to Mendel, the expected phenotype will have phenotypic ratio of 1:2:1
