Which characteristic of DNA determines the variation of genetic expression in phenotypes?
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
How long does the DNA remain in the sperm?
DNA always remains in the sperm, that is how variation happens.
Which processes contributes directly to genetic variation?
DNA Replication
What role does deoxyribose play in DNA?
It is the sugar in DNA
How do chromosomes and genes play a role in the genetic variation of offspring?
DNA contain many genes. and with 2 different parents with many different genes and traits of their own, the number of possible combination is enormous
What is the role of crossing over In genetic variation?
to make sure that tetrads cross over and swap DNA, giving the offspring similar DNA to the parents. im pretty sure this is right :)
What is the role of crossing in ensuring genetic variation?
to make sure that tetrads cross over and swap DNA, giving the offspring similar DNA to the parents. im pretty sure this is right :)
What is the role of crossing-over in ensuring genetic variation?
to make sure that tetrads cross over and swap DNA, giving the offspring similar DNA to the parents. im pretty sure this is right :)
Which characteristic of DNA determines the variation of genetic expression in phenotypes?
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
A genetic characteristic of the individual?
You can inherit height, hair color, and eye color.
How long does the DNA remain in the sperm?
DNA always remains in the sperm, that is how variation happens.
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
What contributes to genetic variation?
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
Which processes contributes directly to genetic variation?
DNA Replication
Mutation is the occurrence of?
random changes or variation in a DNA sequence
Where does variation occur?
Variation or mutation occurs within the DNA. It is a natural result of the replication process, or the copying of one DNA strand to make new DNA during reproduction. If the new mutation ends up making some kind of variation that does not kill the organism, then the variation will be passed on to new generations. This is how new traits are formed. When the variation is actually more useful than a trait that the organism's parents had, that new variation will be passed along as a survival trait.
Naturally occurring methods of recombining DNA within a species to increase variation include all BUT?
dna cloning
