Question

In a monohybrid cross pink coloured flowers are dominant over white coloured flowers.if parents belonging to pure breeding dominant trait and pure breeding recessive trait are crossed what will be the phenotype of F1 generation . if F1 generation plants are self-fertilised what would be the phenotypic ratio in F2 generation? explain with an illustration

Answer 1

if the parents are pure breed and white is dominant Then the F1 generation wud have all right.

Answer 2

The 3:1 phenotype proportion saw in the F2 is reliable with the guideline of isolation. Isolation of matched qualities in heterozygous F1s to deliver a 3:1 phenotype and 1:2:1 genotype proportion.

As indicated by the theory of isolation, each of the three conceivable genotypes ought to be delivered in the F2 age.

Hope this answer is right and get clear ideas on reading it with no risk and trouble of it.
