heterozygotes
different phenotype
true breeding homozygotes.
Chromosomal number in a cell of a flowering plant is
Definitions / Explanation : Homozygous
Give differences : Homozygous and Heterozygous
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:
Cross between the pure tall plant from $F_1$ and dwarf plant will give
