Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
Why is it that lamarck's suggestion that organisms arise spontaneously and then become increasingly more complex is not supported by the theory of natural selection?
Because lamarck thought that traits organisms aquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, aquired traits cannot be passed on to offspring, only traits determined by DNA can.
How does the range of phenotype differ between single-gene traits and polygenic traits?
Single gene traits are either one type or another,for example everyone is either (ABO System) group A,B AB or O with no intermediates - this shows discontinuous variation. In polgyenic traits, continuous variation is shown and there is a range with no discrete categories - height
What are an individual's observable traits called?
genotype or phenotype
How would vestigial traits be explained if evolution occurred via inheritance of acquired characters as proposed by Lamarck?
as a change in an individual's phenotype in response to an environmental challenge
Who determined that individual traits are determined by discrete factor' in what year?

What are some unique traits about Hades?
These are to be determined by the individual.
How is a trait determined?
Genetic traits are determined based on the genes an individual inherits from his parents. All an individual's genes determines his genotype, while factors such as dominance and recessiveness determine phenotype.
What are heredity factors determined at conception?
Heredity factors determined at conception include the genetic material passed down from the parents, such as DNA sequences and genes. These factors influence physical characteristics, behaviors, and predispositions to various health conditions in an individual. They play a significant role in shaping an individual's traits and development throughout their life.
Which discovery is credited to Gregor Mendel?
Gregor Mendel is credited with the discovery of the basic principles of heredity through his work with pea plants, which laid the foundation for the field of genetics. He demonstrated that inheritance follows certain patterns and is determined by discrete units that we now call genes.
What does physical traits means?
Physical traits refer to characteristics that can be observed in an individual's physical appearance, such as height, weight, eye color, hair color, and facial features. These traits are determined by a combination of genetics and environmental factors.
What are traits that are gained during an organism's life and not determined genetically?
Examples of traits gained during an organism's life (acquired traits) include skills learned through experience, such as playing an instrument or riding a bike. Additionally, environmental factors like exposure to sunlight can affect skin tone. These traits are not determined by an organism's genetic makeup and are developed during an individual's lifetime.
Gregor mendel proved that the inheritance of genetic traits is determined by?
Gregor Mendel's experiments with pea plants demonstrated that inheritance of genetic traits is determined by discrete units or factors (now known as genes) that are passed from parents to offspring. Mendel's work laid the foundation for the science of genetics.
What is a physical appearance of an individual is determined by the alleles that code for traits?
Physical appearance is determined by the combination of alleles inherited from parents, which code for traits such as eye color, hair color, and height. These alleles interact in complex ways to produce a diverse range of physical characteristics in individuals. The expression of these traits can also be influenced by environmental factors.
What determines which traits in a population are favorable and which are unfavorable?
Traits in a population are determined to be favorable or unfavorable based on how they affect an individual's ability to survive and reproduce in a given environment. Favorable traits increase an individual's chances of survival and reproduction, while unfavorable traits decrease these chances. Natural selection acts on these traits, leading to the evolution of populations over time.
What heredity refers to factors determined at conception?
Heredity refers to the passing of genetic information from parents to offspring at the time of conception. These genetic factors play a significant role in determining an individual's physical traits, behaviors, and susceptibility to certain diseases.
What decides a trait?
A trait is determined by a combination of genetic factors and environmental influences. Genes code for specific traits, but the expression of those genes can be influenced by the environment in which an individual lives. This interplay between genetics and the environment ultimately shapes an individual's traits.
