How to carry out a Monohybrid cross?
The monohybrid cross is carried out by carrying out following steps:
- Select two parent organisms with differing traits controlled by a single gene.
- Ensure one parent is homozygous dominant, and the other is homozygous recessive for that gene.
- Cross the parents, allowing for controlled pollination or mating.
- Observe the offspring (F1 generation), which will all be heterozygous for that gene.
- Allow the F1 generation to self-pollinate.
- Observe the F2 generation to determine the phenotypic ratios.
- Analyze the data and compare the observed ratios to Mendel’s principles of inheritance.
Monohybrid Cross – Inheritance of One Gene
Monohybrid cross occurs when two organisms with contrasting variations at a particular genetic locus are crossed. The traits being studied are influenced by multiple variations at a single gene location. The resulting offspring, known as the F1 generation, will all be heterozygous and express the dominant trait, masking the recessive trait. The monohybrid cross demonstrates Mendel’s law of dominance.
