Answer 1

by crossing two homozygous individuals wid one or more set of contrasting characteristics

Answer 2

mental two varieties of this plant sowing 7 pairs of contrasting features mental crossed your breathing varieties first by taking only one feature at a time that is monohybrid cross and then by taking two features together that is dihybrid cross it ride with all the 7 features and his observations were familiar for all
up your building plan wearing terminal flowers was Cross pollinated with the pure breathing plant having axillary flowers the resulting fees after sowing produced all plans with Aja flowers only when the hybrid plants with self pollinated they produced in F2 generation plants with axillary flowers and plants with terminal flowers in the ratio of 3 is to 1 days were the visible forms of which we call the fanatics out of the is the 1 bit terminal flowers in subsequent generation produced or all plants with terminal flowers only.out of the other remaining tree with axillary flowers 1 produced all plants with axillary flowers only two again produced in the same ratio 3 is to 1 as was in F2 generation these kind of ratio obtained by crossing for two different traits of a single character is known as monohybrid ratio the consisted of the following phenotypic ratio equal to 3 is to 1 genotypic ratio is equal to 1 is to 2 is to 1
