Question

In a cross a violet flower plant was crossed with a white flower plant.(a)name the type of cross.
(b)write the genotype of F1 progeny.
(c)write the penotype and genotype ratio obtained in F1. (d)How many plants were homozygous round in F2.
for class 10th

Answer 1

A)monohybrid because we are dealing with one character.

B) genotype F1 all are heterozygous violet coloured (violet cause its dominant) (Vv) V for violet v for white

C)phenotypic ratio all are violet

Genotypic ratio all are

hetero zygous violet flower

bearing plants ( Vv )

D) in F2 generation homozygous round? We are dealing with colour of flowers. Monohybrid cross deals only with one character.

SO assuming that by round you mean violet because it is dominant.

1 homozygous violet and 1 homozygous white

2 heterozygous violet

hope this helps☺

All the best
