The correct answer for this question is Fomite transmission. Fomite transmission refers to the transmission of communicable diseases unto surfaces wherein individuals may be able to come in contact with the disease and be able to get infected with it, such as the common cold. When a person with a cold touches something or comes in contact with an individual he or she may infect the person who came in contact with her, either through touch or by things.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1
