Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The ability of an oranism to successfully pass on its genes to offspring is termed
A
fertilization
B
fitness
C
compatibility
D
natural descent
Explanation: 

Detailed explanation-1: -Biological fitness is defined as an organism’s ability to pass its genetic material to its offspring. Species that are more “fit” can pass on their genes and ensure their survival. Fitness evolution is when a species biological fitness can change from one generation to another.

Detailed explanation-2: -Explanation: The term “fitness” in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring.

Detailed explanation-3: -Fitness (often denoted. or in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype.

Detailed explanation-4: -Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group). Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Detailed explanation-5: -In the crudest terms, fitness involves the ability of organisms-or, more rarely, populations or species-to survive and reproduce in the environment in which they find themselves 6–9. The consequence of this survival and reproduction is that organisms contribute genes to the next generation.
