Biology Question on Principles of Inheritance and Variation
Which of the following is genotypic ratio of Mendel?s monohybrid cross?
A
1:03
B
3:01
C
1:02:01
D
1 : 1 : 1 : 1
Answer
1:02:01
Explanation
Solution
Monohybrid cross is a cross made to study simultaneous inheritance of a single pair of Mendelian factors. In other words, the cross in which only alternate forms of a single character are taken into consideration is called monohybrid cross. The Fprogeny shows genotypic ratio of 1 : 2 : 1 where, one homozogous dominant, two heterozygous dominants and one homozygous recessive is obtained.
