What is $F_{2}$ generation?

Give reasons why acquired characters are not inherited.

What is the scientific name of the human species?

Why did Mendel choose the pea plant $(Pisum \text{ } sativum)$ for his experiments?

According to the evolutionary theory,the formation of a new species is generally due to:

$A$ pea plant with blue colour flower denoted by $BB$ is cross-bred with a pea plant with white flower denoted by $ww$.
$(a)$ What is the expected colour of the flowers in their $F_{1}$ progeny?
$(b)$ What will be the percentage of plants bearing white flower in $F_{2}$ generation,when the flowers of $F_{1}$ plants were selfed?
$(c)$ State the expected ratio of the genotypes $BB$ and $Bw$ in the $F_{2}$ progeny.
