explain monohybrid cross in a pea plant taking any one character class 10
Answers
A cross between two types of plants of same species considering only the transmission of one character is called monohybrid cross. For example, a cross between tall pea plants and dwarf pea plant that is considering only the height of the parents is a monohybrid cross. It will result in the formation of tall offsprings but they will be hybrid.
Representation of the monohybrid cross: character in focus is the height
Parents- TT X tt
(Tall) (dwarf)
F1 - Tt
(Heterozygous tall)
On selfing:
Tt X Tt
F2
- TT Tt Tt tt
Phenotypic ratio- 3 tall: 1 dwarf
Genotypic ratio- 1 homozygous tall: 2 heterozygous tall: 1 homozygous recessive
