How does natural selection favor an organism's heritable trait?
Natural selection favors a trait by increasing its frequency in a population. Natural selection is differential reproductive success. If one variant of a trait enables an organism to have and raise more offspring successfully than other variants in a particualr environment, then it will become more common in the population.
What is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.
What is mass selection in plant breeding?
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding
Suppose a variation makes an individual member of a species better adapted to its environment how might that variation affect the individuals reproduction?
their offspring will inherit their favorable traits
If an organism reproduces asexually, it’s offspring will be?
Clones
How does natural selection work for or against an organism?
Natural selection reduces the number of fertile offspring an organism may raise.
Is natural selection the process by which factors in an organism's competition determine whether or not the organism will be able to produce offspring?
yes it is
How do successful adaptations improve an organism's fitness?
An organisms fitness is it's ability to survive and reproduce. Adaptations help an organism do so. According to Darwin, natural selection plays a big part in the adaptations that help an animal survive. Natural selection is basically "the best qualities win and reproduce". Over time, the qualities that survived become adaptations, shaping themselves to the changing environment. Because the best qualities lead to successful adaptations, the "favorable" organism will survive and reproduce, increasing its fitness.
Why are only inherited traits not acquired one necessary for the process of natural selection?
Because the offspring of an organism with a desirable inherited trait is more likely to survive than the offspring of an organism with a desirable acquired trait (because the offspring of an organism with a desirable acquired trait will not have its parent's desirable trait).
What idea says that a type of organism that is better able to survive in its environment than another type of organism will produce more offspring and become predominant?
Natural selection.
How does natural selection favor an organism's heritable trait?

When physical or behavioral adaptations are passed down from one generation to the next because that characteristic helps the organism survive better in its environment it is called?
Natural selection.
What is the difference between selective breeding and natural selection?
In natural selection, the animals take time and evolve slowly. In selective breeding, humans can transfer genes from one organism into another organism.
What mutation affects an organism's offspring?
mutation can affect an organism's offspring
How did Lamarck's ideas differ from Darwin's?
Lamarck believed an individual organism acquired traits during its lifetime and passed those traits on to its offspring. He lacked support for his ideas. Darwin documented how inherited traits could be passed on by natural selection, that adaptations that give an organism an advantage is passed on through subsequent generations and becomes more common. He had evidence for his ideas (finches, tortoises…).
Organism A reproduces by budding Organism B reproduces through fission Each Organism reproduces an offspring in 12 hours After 36 hours which organism will have more offspring?
if both organisms repoduce an offspring every 12 hours then they would have the same number of offspring neither would be greater.
What two kinds of adaptations are there?
The two kinds of adaptations an organism can have is a behavioral or a physical adaptation. These both help the organism survive.
