Assertion : Cross of $F_1$ individual with recessive homozygous parent is test cross.
Reason : No recessive individual are obtained in the monohybrid test cross.
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:
Definitions / Explanation : Filial progeny/F1 generation
Some pure black mice were mistakenly mixed with hybrid black mice. The quickest way to discover whether one individual black mouse is pure is
The important things to remember are that chromosomes as well as genes occur in ...$A$.... The two alleles of a gene pair are located on homologous sites on ...$B$... chromosomes
Choose the correct choice for $A$ and $B$
