What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Is genetic recombination a major source of variation among organisms?
Yes.
What is the ultimate source of genetic variation and the bases for the diversity of life on earth?
mutation
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Why are mutations considered a source of heritable variation in organisms?
Mutations are considered a source of heritable variation in organisms because they are changes in the DNA sequence that can be passed down from one generation to the next. These changes can lead to differences in traits and characteristics, allowing for genetic diversity within a population.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
What is the major source or variation among organisms?
The major source of variation among organisms is genetic variation, which arises from mutations, gene flow, and sexual reproduction. Mutations introduce new genetic material, while gene flow allows for the exchange of genes between populations. Sexual reproduction combines the genetic material of two parents, leading to unique combinations of traits in offspring. Together, these processes contribute to the diversity of traits observed in populations, enabling adaptation and evolution.
Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
What is the source of genetic variation that refers to random error in the genetic code?
Mutations
Which of the following is least likely to be a source of genetic variation among living organisms?
Things that kill the organism, such as, immature lungs at birth.
Which of these is not a source of genetic variation in a population?
The answer is sexual reproduction
