the second generation ratio of a monohybrid cross is
Monohybrid cross This cross is based on the first law of genetics i.e Law of Segregation A monohybrid cross is a mating between two individuals with different variations at one genetic chromosome of interest.[1][2] 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 homozygous or 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.
