The Smith family is afflicted with a genetic disorder known as Pinocchio nose syndrome, which causes affected adults to grow nos

es in excess of five inches long. 100 members of the Smith family show up for a family reunion. Of the fifty-three women, thirty-seven have unusually large noses. Of the forty-seven men, thirty-six have an enormous nose. Based on these figures, Pinocchio nose syndrome is probably
A)88dominant and sex-linked.
B) recessive and sex-linked.

<span>The answer is letter B.

Since both sexes in the family are affected of the syndrome, it is considered as a recessive and sex-linked genetic trait. This simply means that the disease was passed down through families through one of the X or Y chromosomes (sex chromosomes). This occurs even if one parent has a normal gene but the other has an abnormal gene that carries the disease, the abnormal gene then dominates.<span>

Mendel's experiments with pea plants demonstrated the law of dominance: trets are inherited as dominary and
puteri [66]

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

<h3><u>Explanation:</u></h3>

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.
