Answer:

They are used as an indicator organism for pathogenic bacteria.

Coliforms thrive in exact environmental conditions like other pathogenic bacteria, thus often used to indicate whether they are bacteria found in drinking water and swimming pools that might end up causing infections.

Kobotan [32]

Answer:

C. rr

Explanation:

The dominant genotype will always be denoted by the capital version, or in this case R.

The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.

The last box, rr, would be the one that gives the wrinkled phenotype.

In this case, by ratio, wrinkled phenotype show up 25%

This type of inheritance pattern shows BOTH traits in possible offspringand is not a blending or intermediate
olganol [36]

Answer:

The correct answer is - d. codominance.

Explanation:

Complete dominance is the pattern of inheritance where one allele masked the other allele completely in a heterozygous condition. Incomplete dominance is a pattern of inheritance where both the alleles blend or form intermediate phenotype in heterozygous condition.

The codominance pattern of inheritance is similar to the incomplete dominance but instead of making a blend of both alleles, it expresses both alleles together in patches or pattern.
