When a gene exists in more than one form, the different forms are called
A common test to find the genotype of a hybrid is by
In a monohybrid cross of plants with red and white flowered plants, Mendel got only red flowered plants. On self-pollinating these $F_1$ plants got both red and white flowered plants in $3:1$ ratio. Explain the basis of using $RR$ and $rr$ symbols to represent the geno type of plants of parental generation.
A cross between a homozygous recessive and a heterozygous plant is called
