Question

Monohybrid ratio is depicted by

• A. $9 : 3 : 3 : 1$
• B. $3 : 1$
• C. $3 : 4$
• D. $9 : 4 : 4 : 2$

Answer 1

Answer: (B)

$3 : 1$

Answer 2

When a cross is made between individuals, considering only a single pair of contrasting characters it is called monohybrid cross. In F, generation dominant character is expressed while recessive character is hidden although both characters are present in $F_1$ hybrid. If self pollination in plants of $F_1$ generation is made, these characters segregate in $3 : 1$ phenotypic ratio in $F_2$ generation.
