When an individual has both alleles of a contrasting character,it is said to be:

What will be the phenotypic ratio of the offspring produced from the cross $Tt \times tt$?

From a cross $Aa BB \times aa BB$,what genotypic ratio will be obtained in the $F_1$ generation?

In pea plants,yellow seeds are dominant over green seeds. If a heterozygous yellow-seeded plant is crossed with a green-seeded plant,what will be the expected ratio of yellow to green-seeded plants in the $F_1$ generation?

How many types of gametes can be produced by an individual with the genotype $AAbb$?

When a heterozygous tall plant is crossed with a homozygous dwarf plant,what will be the proportion of dwarf progeny in the next generation (in $\%$)?
