Monohybrid Inheritance

1. Worked with peas that have both female and male parts; stamens and carpels.
2. He cross-pollinated the pure-breeding pea plants by his own.
3. The fertilised gametes become seeds and the seeds are planted.
4. He selects the simple and distinguishable traits such as the colour of flowers, the stem length, seed shape, seed colour, colour of pods, pod shape and the position of flowers.
5. He found out that the first generation of offsprings carries the same trait as parents.
6. Become a stepping stone in the study of inheritance.

Occupy specific positions in chromosomes

Alternate forms of the same gene occupying on the same positions on a certain pair of chromosomes

Observable/measurable character

Combination of alleles carried by the organism

Manifested in the appearance of the phenotype

Appears in the phenotype if it does not pair with the dominant allele

Both alleles at a given pair of loci are the same

Example: homozygous dominant (TT) and homozygous recessive (tt)

The alleles at a given pair of loci are the different

Example: heterozygous dominant (Tt)

1. Studies of a pair of contrasting traits of a character.
2. The original parents denote as P generation.
3. The result of the parental cross appeared as the F1 generation.
4. The plants of F1 generation allowed to cross-pollinate to produce the F2 generation.
