What does natural selection directly work on?
Natural selection directly works on the heritable traits of organisms that impact their ability to survive and reproduce in a given environment. Organisms with traits that enhance their survival and reproductive success are more likely to pass those traits on to the next generation.
What is the name given to the collection of traits exhibited by an organism?
Phenotype.
How do mutations relate to natural selection?
Mutation, a copying error in the replication of DNA, can give rise to variation in an organisms phenotype and if this new phenotype is beneficial to survival and reproductive success ( as little as 1% ) it will be selected naturally against the immediate environment, then if this so selected organism leave many descendents with the same beneficial traits then the populations gene pool will change in allele frequency and you have evolution. ( a 19th century sentence Darwin would be proud of! )
What is the name given for the actual physical trait of a person?
The name given for the actual physical trait of a person is "phenotype." This term refers to the observable characteristics of an organism, which are determined by both genetic and environmental factors.
Which term is given to the measure of the proportion of offspring that a particular phenotype will contribute to the next generation?
Progeny
What a ratio?
A genotypic -ratio reflects the genetic configuration of an individual in the population. Several genotypes are possible in a phenotype and the ratio in which the genotypes segregate in a given phenotype is known as its genotypic ratio.

Does phenotype determine genotype?
It is a false statement that "phenotype determines genotype". In fact, it is the opposite. A genotype is the genetics or "instructions" that determine the phenotype. The phenotype is the actual appearance, ex: blue eyes, that is created by a given genotype.
The physical appearance of the entire set of chromosomes of a given animal?
The physical appearance of the entire set of chromosomes of a given animal is a phenotype. A phenotype is a trait that you can observe like the color of a persons eyes.
Is the set of all common factors of two given natural numbers infinite?
No.
What is the name given for the actual physical trait of a person?
The name given for the actual physical trait of a person is "phenotype." This term refers to the observable characteristics of an organism, which are determined by both genetic and environmental factors.
What is the probability that the offspring of a homozygous dominant individual and a homozygous recessive individual exhibit the dominant phenotype?
Given those conditions, the offspring have a 50% chance of demonstrating the dominant phenotype and a 50% chance of demonstrating the recessive phenotype.
How phenotype influence adaptation?
Phenotype influences adaptation by determining an organism's physical characteristics, such as its shape, size, and color. These characteristics can impact an organism's ability to survive and reproduce in a given environment, leading to the selection of traits that are better suited for the specific conditions. Over time, natural selection acts on these traits, driving adaptation by favoring phenotypes that provide a reproductive advantage.
Which term is given to the measure of the proportion of offspring that a particular phenotype will contribute to the next generation?
Progeny
Natural selection acts directly on phenotype whereas evolution acts directly on?
Natural selection acts directly on phenotype, which refers to the observable traits of an organism. In contrast, evolution acts directly on the genetic makeup of populations over time, as changes in allele frequencies occur due to processes like natural selection, mutation, gene flow, and genetic drift. Thus, while natural selection influences which phenotypes are favored in a given environment, evolution encompasses the broader changes in genetic composition that drive the adaptation and diversification of species.
