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

A

$TT, Tt$ and $tt$

B

$TT$ and $tt$ only

C

$TT$ and $Tt$ only

D

$Tt$ and $tt$ only

Solution

The leaf colour of certain plants is controlled by one gene. For that gene, the allele $G =$ orange and $g =$ green. You have a plant with orange leaves, but do not know whether that plant's genotype is $GG$ or $Gg.$

If you cross your unknown plant with one of the plants whose genotype is listed below, you will be able to determine your unknown's genotype. With which plant would you cross it?
