There are three categories of point mutations:
- Nonsense - the mutated codon is now a stop codon, severely truncating the polypeptide. The protein will no longer function.
- Missense - the mutated codon now codes for a different amino acid, which alters the structure of the polypeptide. If the protein is still functional, it may be inhibited by its different structure, seen in sickle cell anemia. The changed polypeptide may also benefit the organism with a positive phenotype, which fuels evolution.
- Silent - because different arrangements of bases can code for the same amino acid, a mutated codon could code for the same amino acid as before. Effectively, the mutation did not change anything about the polypeptide ― hence, it is "silent."

How many of the possible outcomes is for the genotype FrFr?
One: FrFr.
Which type of mutation will have the most evolutionary consequence?
A frameshift mutation will have the most serious effects.A frameshift mutation is a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three.Divisible by three is important because the cell reads a gene in groups of three bases.Each group of three bases corresponds to one of 20 different amino acids used to build a protein.If a mutation disrupts this reading frame, then the entire DNA sequence following the mutation will be read incorrectly.
What are four types of chromosomal mutations?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
If someone cross a purebred mother with type B blood and a father with type AB blood what are the possible blood type outcomes of their offspring?
Based on Punnett squares, the possible outcomes are A, B and AB.
What are the three outcomes of meiosis?
Three outcomes of meiosis: it reduces chromosomes to the haploid number, it provides genetic variation, and it ensures the correct distribution of chromosomes into the resulting cells.
How many possible outcomes of tossing three coins?
There are 23 = 8 possible outcomes.
How do you draw a table of three teams with three possible outcomes?
With considerable difficulty since there are a lot more than 3 possible outcomes.
What are 2 possible outcomes of competition?
Three possible outcomes:WinLooseDraw
What are three possible outcomes to a two system equation?
THREE
How many outcomes are possible if a six sided cube is tossed three times?
18 outcomes
How do you do a probability?
Number of useful outcomes over number of possible outcomes and simplify it if you can. Imagine you want an even number and you roll a die. There are 6 possible outcomes and three of them are useful outcomes (outcomes we want). 3 6 Simplify it and you get 1 2
If you flip a coin 2 times how many possible outcomes are there How many combinations?
Four outcomes, three combinations.
If there are three coins and each is flipped once how many possible outcomes are there?
There are two outcomes for each coin and three coins; 2 x 2 x 2 = 23 = 8 outcomes.
What are possible outcomes if you roll three dice?
C(8,3) = 56
How many possible outcomes if each coin is flipped once?
We use three coins (quarter, nickel, dime) each are flipped only once. We get 8 possible outcomes (or four outcomes as an alternative).
A sweater comes in 3 sizes and 6 colors what is the number of possible outcomes?
The number of outcomes depends on what the experiment is! If the variable of interest is the size, there are just three outcomes. If the variable of interest is price, then there is not enough information to determine the possible outcomes.
A possible result of an experiment?
when you toss a coin three times, the total number of possible outcomes is
