An angiosperm plant having red coloured flowers when crossed with the other having the same colour produced 40 progenies, out of which 30 plants were with red coloured flowers 10 plants were with white coloured flowers. Find out:
(a) What is the possible genotype of parent plants?
(b) Which trait is dominant and recessive?
(c) What is this cross called as and what is its phenotypic ratio?
a) The possible genotype of parent plants are 'Rr' and 'Rr' , 'R' refers red colour trait and 'r' refers white colour trait.
b) Trait 'R' is the dominant trait whereas trait 'r' is the recessive trait.
c) This cross is called monohybrid cross.
The phenotype ratio is - 3:1
