List various conclusions drawn from a cross between red flowering plant and white flowering plant which give same genotypic and phenotypic ratios of 1:2:1 in `F_2` generation.

in dog flower, a red flowered plant is crossed with a white flowered plant. what will be the phenotypic ratio in F_2 generation?

Work out the cross to show the phenotype and genotype ratio of F_1 and F_2 generations.

phenotypic ratio in plant Snapdragon in F_2 is:

Two Antirrhinum plants, one with red flowers and the other with white flowers were crossed. Show the possible genotypes and phenotypes of the progeny of F_1 and F_2 generations using the Punnette square. Explain the pattern of inheritance.

The phenotypic ratio in the F_2 generation of a dihybrid cross is :

How did he disprove Mendelian dihybird F-2 phenotypic ratio of 9: 3: 3: 1? Explain giving reasons.

A cross between a red flower bearing plant and a white flower bearing plant of Antirrhinum majus produced all plants having pink flowers. Work out a cross to explain how is this possible?

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.

In antirrhinum (sanpdragon) all its flower was crossed with a white flower and in a F_1 generation pink flowers where obtained. when pink flower were selfed the F_2 generation show white, red and pink flowers. choose the incorrect statement from the following:

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.
