How many characters are true regarding incomplete dominance from given options?

i) Phenotype does not resemble either of the two parents and is in between the two

ii) The inheritance of flower colour in the dog flower is an example of it.

iii) In a cross between true – breeding red flowered (RR) and true breeding white-flowered plants (rr), the (Rr) is pink.

iv) When the of red – flowered (RR) and white flowered (rr) plants is self – pollinated, it resulted in the ratio 1 (RR) Red : 2 (Rr) Pink : 1 (rr) White.

v) Genotypic ratio is same as Mendelian monohybrid cross

i) Phenotype does not resemble either of the two parents and is in between the two.

True. In incomplete dominance, the phenotype of the heterozygous individual is intermediate between the phenotypes of the two homozygous parents.

ii) The inheritance of flower color in the dog flower is an example of it.

True. The dog flower (or any other species) exhibits incomplete dominance in its flower color inheritance.

iii) In a cross between true breeding red-flowered (RR) and true breeding white-flowered plants (rr), then (Rr) is pink.

True. In incomplete dominance, the heterozygous genotype typically results in an intermediate phenotype, which, in this case, is pink.

iv) When the offspring of red-flowered (RR) and white-flowered (rr) plants is self-pollinated, the result is in the ratio 1 (RR) Red: 2 (Rr) Pink: 1 (rr) White.

True. Incomplete dominance often results in a 1:2:1 phenotypic ratio when heterozygous individuals are self-pollinated.

v) Genotype is the same as Mendelian monohybrid cross.

True. Incomplete dominance and Mendelian monohybrid crosses have the same genotype of 1:2:1
