What else can I help you with?
Genetic engineering is the reassortment of chromosomes and genetic information true or false?
True
What is genetic?
Genetics is the study of heredity and the variation in organisms. When studying genetics, you learn about dominant and recessive traits along with much more.
What happens after meiosis to introduce even more genetic variation in sexually reproduced organisms?
fusion of gametes via fertilization
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
What is the reassortment of genetic information which results in variation among organisms called what?
i believe it is crossing over
Genetic engineering is the reassortment of chromosomes and genetic information true or false?
True
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
Molecules responsible for hereditary and variation of organisms?
DNA and RNA are molecules responsible for heredity and variation in organisms. They carry genetic information that is passed down from one generation to the next, and mutations in these molecules can lead to variations within a species.
Is genetic variation found only in wild organisms in nature?
No.
What event in meiosis leads to genetic variation in organisms?
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Is genetic recombination a major source of variation among organisms?
Yes.
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
What is essnetial to evolution?
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
Increased genetic variation often helps organisms withstand changes in the?
Environment
What is an allele and how does it contribute to genetic variation in organisms?
An allele is a variant form of a gene that determines a specific trait. Alleles contribute to genetic variation in organisms by creating different combinations of traits through genetic recombination during reproduction. This variation allows for diversity within a population, which can lead to adaptations and evolution over time.
