Explain the process to understand monohybrid cross of Mendel experiment with a checker board.
Answers
Title:
Monohybrid cross is defined as the type of cross which is made between two parents that are differ from each other only in one heritable characterstics. The hybrid obtained is called monohybrid.
Explanation:
In monohybrid cross one trait is dominant while the other is recessive and is not expressed in the next generation.
The ratio of monohybrid cross obtained in F2 generation is 3:1.
Monohybrid cross of Mendel experiment
Explanation:
In a monohybrid cross, for any character, the F1 generation individual would show one feature of a character as dominant and the other would be recessive. The recessive is not completely lost and it can reapper in the F2 generation. This suggests that there is no blending of Mendelian factors in the F1 generation but they stay together and only one is expressed. So, two or more forms of a single character can exist in a single gene locus of a homologous chromosome within a species that may put different effects on the phenotype of an organism.
In the hybrids between two individual displaying different phenotypes only one character is observable. The observable character is the dominant one and the other is recessive, whose phenotype remains masked in heterozygous condition, but is only expressed in homozygous condition. The phenotypic features in the first filial generation after a cross between a homozygous female and a heterozygous male for a single locus, say height, is as follows:
