When a homozygous red-flowered pea plant is crossed with a white-flowered plant, what color will be produced in the $F_1$ generation?

In Mendel's experiment,he crossed tall and dwarf pea plants to study the inheritance of one.....

$A$ true-breeding plant producing red flowers is crossed with a pure plant producing white flowers. The allele for the red color of the flower is dominant. After selfing the plants of the first filial $(F_1)$ generation,what would be the proportion of plants producing white flowers in the progeny?

If two pea plants with red flowers,whose genotypes are unknown,are crossed,$75\%$ of the offspring have red flowers and $25\%$ have white flowers. The genotypes of the red-flowered parent plants must be:

The crossing of a homozygous tall plant with a dwarf plant in the $F_2$ generation would yield plants in which ratio?

When different alleles of the same gene are present in an individual,the individual is a
