Question

What will be the results in the F2 generation after a monohybrid cross?

all recessive traits

3/4 dominant and 1/4 recessive

all dominate traits

1/3 dominant and 2/3 recessive

Answer 1

Answer:
`\frac34` dominants and
`\frac14` recessive.

Step-by-step explanation:

Mendel's monohybrid cross is definied as

• a genetic combination of two homogeneous genotypes.
• One is dominant(TT) to other (tt-recessive).

Result in F1 generation: 4 dominant(Tt), 0 recessive (tt)

Result in F2 generation: 3 dominant(TT, 2Tt), 1 recessive (tt)

[If one T is present then we call it Tall (Donimant effect), if none then we call it dwarf]

The results in the F2 generation after a monohybrid cross:
`\frac34` dominants and
`\frac14` recessive.
