Question

Explain the results of Mendel's Monohybrid Cross with examples and diagrams.​

Answer 1

Answer:

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)

F

1

- Tt

(Heterozygous tall)

On selfing:

Tt X Tt

F

2

- TT Tt Tt tt

Phenotypic ratio- 3 tall: 1 dwarf

Genotypic ratio- 1 homozygous tall: 2 heterozygous tall: 1 homozygous recessive

Answer 2

Answer:

A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. ... When a cross satisfies the conditions for a monohybrid cross, it is usually detected by a characteristic distribution of second-generation (F2) offspring that is sometimes called the monohybrid ratio.

A monohybrid cross results in a phenotypic ratio of 3:1 (dominant to recessive), and a genotypic ratio of 1:2:1 (homozygous dominant to heterozygous to homozygous recessive).
