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
flowering plant and a heterozygous pink flowering plant, predict the probability of having offspring in rei rowery
0%
25%
50%
100%

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

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.

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !
