The allele for tallness is dominant over that of dwarfness. This is called

If allele for tallness ( TT ) is dominant and dwarfness ( tt ) is recessive , then in cross between _____________ 50 % of the offsprings will be dwarf .

In garden pea, the gene T for tall is dominant over its allele for dwarf. Give the genotypes of the parents in the following crosses. (a) Tall xx Dwarf producing all tall plants. (b) tall xx tall producing 3 tall and 1 dwarf plants.

Some plants occur in one of the two sizes : tall or dwarf. This characteristic is controlled by one pair of genes. Tallness is dominant to dwarfness. Choose suitable letters for this gene pair.

In peas, tallness is dominant over dwarfness, and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated by a dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them Tall, Red = 138 Tall, White = 132 Dwarf, Red = 136 Dwarf, White = 128 Mention the genotypes of the two parents and of the types of four offspring

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.

In a plant , tallness is dominant over dwarfness and red flowers are incompletely dominant over white flowers, the hybrid being pink. How many offsprings will be of tall height with pink flowers from a cross involved two plants each of which is hybrid tall and has pink flowers ?
