Which Of The Following Is The Best Measure Of An Organism’s Fitness? (Solved)

The amount of viable offspring produced by an organism would be the most accurate indicator of its health and fitness.

What is the measure of an organisms fitness?

Fitness is a measure of an organism’s ability to survive and reproduce, with the emphasis on the word “reproduce.” Officially, fitness is defined as the average number of children that organisms with a certain genotype or phenotype leave behind in comparison to the number of offspring left behind by other organisms in the community.

What determines an organism’s fitness quizlet?

The fitness of an organism is defined as the relative capacity of that organism (and hence its phenotype) to survive and reproduce in its natural environment.

What is an organism’s relative fitness measured by?

When the reproductive rate (of a genotype or phenotype) is compared to the maximum reproductive rate (of other genotypes or phenotypes) in a particular population, it is considered a measure of biological fitness. It may be calculated by dividing the absolute fitness of a population by the average number of children produced by that population.

What is fitness the measure of quizlet?

Fitness is a metric for determining reproductive success.

Which of the following most accurately and directly measures an organism’s relative fitness?

When it comes to determining an organism’s relative fitness, which of the following assesses it the most correctly and directly? the proportion of a person’s contribution to the gene pool of the following generation as compared to the proportion of other persons’ contributions

What is biological fitness quizlet?

Fitness on a biological level. The capacity of a person to generate surviving, viable children in comparison to the ability of other individuals in a community is known as reproductive ability.

What ultimately determines an organism’s Darwinian fitness?

Natural selection operates at the level of the individual; it favors individuals who make greater contributions to the gene pool of the next generation, a trait known as an organism’s evolutionary fitness, which is a measure of how well an organism contributes to the gene pool of the next generation (or Darwinian fitness).

How is fitness measured biology quizlet?

The number of offspring produced by a person is measured by his or her biological fitness. A) Populations can evolve, but individuals are incapable of doing so. B) Evolutionary change is not necessarily a result of genetic variations between individuals.

Which organism would be most fit?

The most physiologically fit creature is the one that produces the most fruitful offspring, and this is true for all organisms. Although life span has been shown to be correlated with the number of offspring produced, it is not a direct factor in determining fitness. Because the creature that lives 36 years has generated the greatest number of offspring (6), it is considered to be the most physiologically fit.

What does relative fitness tell us?

Unless we know the fitness of other genotypes, knowing this value for a genotype does not inform us if that genotype is doing poorly or well. The relative fitness of an allele or genotype is a measure of how much fitness it has in comparison to the maximum fitness, and hence whether it will grow or decrease.

What does selection coefficient measure?

With regard to genetics, a selection coefficient is a measure of how much less of an impact a given genotype (genetic makeup) has on the gametes (sex cells) as compared to another genotype in a population.

How is inclusive fitness measured?

Obtaining inclusive fitness entails deducting from reproductive success ‘all components that can reasonably be considered as being due to the individual’s social environment,’ and then adding all effects of the individual on his neighbors, weighted by the coefficient of relationship (r) between them.

What is fitness quizlet?

Define the term “fitness.” – entails some form of physical exertion or exercise Athlete fitness is comprised of the following components: cardiorespiratory endurance, flexibility, muscular strength, and muscle endurance. – all of these features are indicative of a physically fit physique.

What field of biology compares the development of organisms in order to better understand mechanisms of evolutionary change?

When studying species’ development, evolutionary developmental biologists look at how they differ from one another in order to better understand the causes of evolutionary change.

When calculating an allele frequency for a diploid species how many alleles are present for each gene?

An allele is a gene that has several different forms. There are several distinct variants of some genes, all of which are situated at the same place, or genetic locus, on a chromosome as one another. Humans are classified as diploid creatures because they have two alleles at each genetic locus, with one allele acquired from each parent and one allele inherited from the other parent.
