In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is
Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp

Individuals producing an abnormal form of the extracellular matrix protein, fibrillin, is a result of ______.
erastova [34]

Answer:

Indivisuals with producing an abnormal form of extracellular protein fibrillin are suffering from Marfan syndrome ehich is caused by genetic mutation in the FBN1 gene.

Explanation:

Gene mutations in FBN1 gene results in the production of an abnormal extracellular matrix fibrillin-1 protein that cannot function properly. These gene mutations basically reduce the amount of fibrillin-1 produced by the cell, alter the structure of fibrillin-1, or causes the impairment of the transport of fibrillin-1 out of the cell.

As a result, protein is poorly incorporated into extracellular matrix. Hence, indivisuals with Marfan syndrome present following symptoms

Tall stature.

Disproportionately long arms, legs and fingers.

Sternum either protrudes outward or dips inward.

Arched palate and crowded teeth.

Heart murmurs.

Extreme nearsightedness.
