Two types of gene mutations are chromosomal and point mutation. Chromosomal mutation alters a cell's chromosomes, while point mutation replaces single-base pair nucleotides with other nucleotides found in RNA or DNA.

What are 3 types of mutation?
Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
What are two sources of genetic variation?
Natural and Artificial Selection
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
What are two types of frame shift mutations?
"I believe there is insertion and deletion, (one kind), and substitutions. (the second kind)" This answer is incorrect, the two types of frameshift mutation are insertion and deletion, these both alter the translation reading frame. A substitution point mutation in DNA is referred to as a single-nucleotide polymorphism and does not result in any change to the translational reading frame. insections and deletions are two types of frameshift mutations
Beadle and tatum's hypothesis?
beadles and tatums hypothesis was that mutations occured when one gene made two poteins it was evidential that beadles and tatums hypothesis had altered in 1941 when tatum found a mutation in one of there experiments.
Can you list Two sources of variation?
Mutations, recombination, gene flow.

What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
Name two major types of mutations What do they have in common How are they different Give an example of each?
Gene and chromosomal; both change DNA sequence that affects genetic information. Gene mutations involve a change in one ore several nucleotides in a single gene, whereas chromosomal mutations involve changes in the number or structure of whole chromosomes
What are the two types of gene shuffling?
Gene shuffling means the genetic recombination and mutations of a gene pool of a species where genetic recombination is the mixture of parent alleles that are passed on and the mutations are the random changes in an organisms DNA that are passed on.
What is driver mutation?
The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.
Is it true that only mutations in gametes can be passed from parent to offspring?
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
Would all mutations to DNA happen to a gene?
all mutations in terms of DNA happen in a gene. here it has to be noted that a gene is made up of two strands of nucleotides which are made up of amino acids. when mutations occur the sequence of nucleotides may change. sometimes a nucleotide may become missing hence the sequence of the strands change. mutations can be harmful but also very beneficial.
What are the two types of mutations in gamete cells?
Deletion or Insertion

Natural and Artificial Selection

Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
