In a monohybrid cross, pink coloured flowers are dominant over white coloured flowers. If parent plants belong to pure breeding dominant, trait and pure breeding recessive trait, what will be the phenotype or morphological feature of F_1 generation ? If F_1 plants are self-fertilised, what would be the phenotypic ratio, or how many dominant and recessive traits will be produced in the progeny ? Explain with an illustration .

In monohybrid cross of red and white flower, Mendel got only red flower. On setting the F_1 plants having red flower he got both plants with red and white flower. Explain the basis of using RR and rr symbols to represent the genotype of plants of parental generation.

If F_1 generation has all tall progenies and ratio of F_2 generation is 3:1 (Tall:Dwarf),then it proves:

A true breeding tall plant is crossed with a true breeding dwarf plant. F_1 progeny is 100% tall and F_2 has tall: dwarf in the ratio 3:1 Name the patterns fo inheritance in which the ratio deviates from above. Also mention the deviated phenotypic ratio.

A plant with red flowers was crossed with another plant of same species with white lowers, the plants of F_1 generation bore pink flowers. Explain the pattern with the help of a ross.

Two heterozygous parents are crossed. If two loci are linked what would be the distribution of phenotypic feature in F_1 generation for a dihybrid cross?

In peas, tallness is dominant over dwarfness and red colour of flowers is dominant over the white colour. When a tall platn bearing red flowers was pollinated with dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in number (a)Tall, red - 138 (b)Tall, white - 132 (c)Dwarf, red - 136 and (d)Dwarf, white - 128. Mention the genotypes of the two parents and of the four offspring types.
