Choose the best definition of allele.

a. one of several possible versions of a gene, which each produce a different phenotype
b. the process of fertilizing a plant with pollen from another plant
c. a set of genes that are located on the same chromosome and so are tightly linked
d. an organism that's purebred for a given trait

The correct answer is option A. one of several possible versions of a gene, which each produce a different phenotype.

Explanation:

The variant forms of a particular gene which form different phenotype are known as an allele. Alleles can be dominant or recessive in nature.

If any organism is heterozygous than the dominant allele will be expressed phenotypically.

Thus, the correct answer is an option is A.

you know they are heterozygous for a trait because they have it as jj or jj.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
