When Mendel crossed true breeding white-flowered strain of peas with a true breeding red-flowered strain, individuals in the $F_2$ represented
White-flowered plants
Red-flowered plants
Red-flowered and white-flowered plants in the ratio $3 : 1$
Red and white-flowered individuals in the ratio $1 : 1$
Define and design a test - cross?
$BB =$ for black colour alleles
$bb =$ for brown colour alleles
Offspring of a cross between a black mouse and brown mouse allowed to interbreed than find out the percentage of black coat in them
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?
Two pea plants were subjected for cross pollination. Of the $183$ plants produced in the next generation, $94$ plants were found to be tall and $89$ plants were found to be dwarf. The genotypes of the two parental plants are likely to be
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
