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
$TT$ and $tt$
$Tt$ and $Tt$
$Tt$ and $tt$
$TT$ and $TT$
What is the cross between the progeny of $F_1$ and the homozygous recessive parent called ? How is it useful ?
The cross used to ascertain whether the plant is homozygous or heterozygous is
Chromosomal number in a cell of a flowering plant is
In a zygote if the number of alleles is two in alternate forms, the expression of adult would be
If at a tall plant is crossed with a dwarf plant and obtained progeny is half tall and half dwarf plants. Then the genotype of progeny will be
