Mendel's experiments with pea plants demonstrated the law of dominance: trets are inherited as dominary and
recessive alleles, and the dominant allele for trait can mask the presence of the cessive altele. Occasion lly, that
law is contradicted: offspring exhibit a blend of the parents' traits. For example a red flowering plant
w crossed
with a white flowering plant would produce a plant with pink flowers. In a genetic ross between botrygous red

Respuesta :

The probability of progenies to have red flower is 50%.

Explanation:

The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.

Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.

Let the allele for dominant character i.e red flower be R and recessive character white be r.

So the genotype for red flowering plant = RR.

The genotype for pink flowering plant =Rr.

The gametes from red flowering plant =R.

The gametes from pink flowering plant =R and r.

So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.

So plants with red flowers will be 50% of the whole progeny.

Answer:

50%  is the answer
