What is incomplete dominance?

Question

What is incomplete dominance?

[In science...referring to genetics]

Answer 1

This means that an individual with both forms of the gene (Rr) will have an intermediate form of the trait -- something in between the two extremes. Ex: Red RR, white rr, Rr pink

Answer 2

Incomplete dominance refer to genetical situation where an organism inherits a blended phenotype, instead of just the dominant trait.

Answer 3

In incomplete dominance (sometimes called partial dominance), a heterozygous genotype creates an intermediate phenotype. In this case, only one allele (usually the wild type) at the single locus is expressed, creating an intermediate phenotype. A cross of two intermediate phenotypes (= monohybrid heterozygotes) will result in the reappearance of both parent phenotypes and the intermediate phenotype.

The classic example of this is the colors of carnations.
R R'
R RR RR'
R' RR' R'R'

R is the allele for red pigment. R' is the allele for no pigment.

Thus, RR offspring make a lot of red pigment and appear red. R'R' offspring make no red pigment and appear white. RR' and R'R offspring make a little bit of red pigment and therefore appear pink.

Answer 4

the easiest way to think of it is as a blending of two traits
say incompletely dominant for a trait that has an allele that makes you blue and one that makes you yellow, so your genotype would be BY, so if you mix blue and yellow you get green
this should not be confused with codominance, where you would see patches of each colour, instead of a blend..ex calico cats that have patches of different colours

Answer 5

see for every character there r 2 genes
one is called dominant & other is called recessive they r called alleles or allelomorphs
there dominant gene shows its effect on that character
eg. for height there r 2 genes
one tall & other short
if tall shows its effect then tall is dominant over short
but some times they get blended up mixed up to give animal of medium height this is called incomplete dominance
eg in snapdragon flower there r 2 allels for colour of flower
one for red flower & other for white flower
but if plant with red flowers is crossed with plant having white flowers we get plant with pink flowers. this is called incomplete dominance
