Answer 2

Given:

A heterozygous violet flowered pea plant is crossed to another homozygous violet flower.

To find:

% of progeny plants will have the recessive trait i.e white flowers.

Calculation:

Violet colour of flowers is a dominant trait.

So, Heterozygous Violet genotype = Vv

Homozygous Violet genotype = VV

So, gametes produced are V and v

Refer to image for table:

Hence , % of progeny plants having recessive trait (i.e. white flowers)

$\rm{\% = \dfrac{no. \: of \: vv \: genotype}{total \: progeny} }$

$= > \rm{\% = \dfrac{0}{4} }$

$= > \rm{\% = 0\% }$

So, final answer is:

$\boxed{ \bf{\% \: of \: white \: flowers= 0\% }}$

• It is also visible from the table that all the F1 progenies have violet phenotype due to dominance of Violet (V) trait.

• So, white flowers are not produced.
