Question

Explain about mendels mono hybrid crossing

Answer 1

This cross is based on the first law of genetics i.e Law of Segregation. A monohybrid cross is a mating between two organisms with different variations at one genetic chromosome of interest. The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. A cross between two parents possessing a pair of contrasting characters is known as monohybrid cross. To carry out such a cross, each parent is chosen to be homozygousor true breeding for a given trait (locus). 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.

Answer 2

That's an interesting question

Mendel discovered Monohybrid cross in pea plants.
He first crossed homozygous (same) female plants with homozygous male. As you may know, genotype of let's say tallness is TT for homozygous dominant tall and tt for homozygous recessive tall

Gametes produced by female parent is T (one because they are homozygous) and by male parent is t. When these gametes are made to fertilize, he observed that the daughter plants produced contained both the gametes of female and male parent Tt, where T was dominant and t was recessive

Cross made between two plants using single defining character is called Monohybrid cross and in this case, he used tall and dwarf
