Someone who is heterozygous for a recessive allele that codes for a disorder of some sort will not express the disorder in his or her genotype, but would be considered a carrier of the allele, and could pass it on to his or her offspring if the other parent is either heterozygous or homozygous for the recessive allele.

kmf Of the 40 specimens of bacteria in a dish,3 specimens have a certain trait. If 5 specimens are to be selected from the dish

almond37 [142]

Answer:

$\frac{C^{3}_1* C^{47}_4}{C^{40}_5}$

Explanation:

It is given that out of 40, total 5 specimen are selected.

Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by

$C^{40}_{5}\\$

Number of specimen with certain trait is equal to 3.

Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest $40-3=37$ specimen.

Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to

$\frac{C^{3}_1* C^{37}_4}{C^{40}_5}$
