Chromosomal number in a cell of a flowering plant is
Only haploid
Only diploid
Many types
None of these
When a heterozygous dominant is crossed with homozygous recessive than ratio of progeny will be
Definitions / Explanation : Filial progeny/F1 generation
Mendel cross tall and dwarf plant. In $F_{2}$-generation the observed ratio was $3: 1$ (tall: short). From this result, he deduced
$I.$ law of dominance
$II.$ law of independent assortment
$III.$ law of segregation
$IV.$ incomplete dominance
Choose the correct option
Which one of the following can be explained on the basis of Mendel's Law of Dominance?
$A$. Out of one pair of factors one is dominant and the other is recessive.
$B$. Alleles do not show any expression and both the characters appear as such in $F_2$ generation.
$C$. Factors occur in pairs in normal diploid plants.
$D$. The discrete unit controlling a particular character is called factor.
$E$. The expression of only one of the parental characters is found in a monohybrid cross.
Choose the correct answer from the options given below:
If a cross is made between $AA$ and $aa$, the nature of ${F_1}$ progeny will be
