Which one of the following represents a test cross?

Mendel was lucky, because

How many types of gametes may be produced by genotype DdEeFf?

When a cross is done between an offspring and it's parent, it is known as

Mendel crossed a pure white-flowered recessive pea plant with a dominant pure red-flowered plant. The first generation of hybrids from the cross should show

How many different types of genetically different gametes will be produced by a heterozygous plant having the genotype AaBbCc?

A cross in which an organism showing a dominant phenotype (genotype unknown) is crossed with the recessive parent in order to know its genotype is called as  

In the monohybrid cross Tt x tt, the phenotypic ratio of the progeny would be 

A dwarf pea plant was treated with gibberellic acid (GA), it grew as tall as the homozygous tall pea plant. If this GA-treated plant is now crossed with a pure tall pea plant then the phenotypic ratio in the next generation is likely to be

From a single ear of corn, a farmer planted 200 kernels which produced 140 tall and 40 dwarf plants. The genotype of these offsprings are most likely
