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.
What causes DNA variation in organisms?
Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.
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 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 genetic variation?

What contributes to genetic variation?
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
What are segments of DNA capable of moving from one area in the DNA to another called?
Segments of DNA capable of moving from one area in the DNA to another are called transposable elements or transposons. They can "jump" to different locations within the genome, causing genetic variation and playing a role in gene regulation and evolution.
Mutation is the occurrence of?
random changes or variation in a DNA sequence
What role does DNA play in genetic inheritance, and how does it determine the traits and characteristics of an organism?
DNA plays a crucial role in genetic inheritance by carrying the genetic information that determines an organism's traits and characteristics. Through the process of gene expression, DNA provides instructions for the production of proteins that ultimately shape an organism's physical and biochemical features. Inheritance of DNA from parents also contributes to the variation and diversity seen in different organisms.
What is genetic variation measured with?
Variation of quantative characters such as littersize and lifetime reproductive output. Variation in protein sequence. Variation in the non-coding regions of DNA
Why are chimpanzees brown and black?
evolution. variation and natural selection. DNA!!!!
What is the purpose of DNA in a short answer?
It creates variation through the genes it codes for. actually, only 3% of our DNA accounts for genes. AP bio!!!!!! It creates variation through the genes it codes for. actually, only 3% of our DNA accounts for genes. AP bio!!!!!!
