What do you understand by monohybrid and dihybrid cross performed by mendal.
Answers
Monohybrid: Definition
In biology, a monohybrid cross is defined as the breeding experiment conducted between parents, which differ in one specific trait ('mono' meaning one). Or in other words, the parents are heterozygous (having dissimilar alleles) at only one locus. Over here, one parent has a dominant gene for a specific phenotypic character (e.g. tall trait), while the other has recessive gene for the particular phenotype (e.g. dwarf trait).
Dihybrid: Definition
Contrary to monohybrid cross, parents that differ in two traits ('di' meaning two) are bred in a dihybrid cross. To be more precise, the parental organisms are heterozygous for two different characters. In this case, one parent has dominant genes for two characters (e.g. tall plant bearing red flowers) and the other parent has recessive genes for the two characters (dwarf plant bearing white flowers) in the chromosome.
