Explain how a mutation in an individual's DNA occurs, and describe the effect it may have on the individual's traits.


Mutation occurs in an individuals DNA when their is a change in genetic material. Their are many kind of mutations including insertion and deletion. They speak for themselve. Mutations are usually harmful but can sometimes be a benefit because it causes immunity. The effect mutation can have on a individuals trait is that it causes a chromosome of a gene to be missing, resulting in incompletence. The effect of this can be seen mutations like Down Syndrome. I hope this helped u because i have been learning about this in my biology class recently.


A Mutation is a shift that generates in an individual DNA sequence, which might be due to the faults when the DNA is comparing or as the result of chemical and physical agents in an environment such as Smog or cigarette smoke or ultraviolet rays.

The most common effect of Mutation on individuals is, it causes both internal and external Mutation.

Cats may have straight or curly ears. A cat with curly ears mated with a straight-eared cat. All the kittens had curly ears. Are curly ears a dominant orrecessive trait? Explain your answer.


I believe that curly ears are dominant because all the kittens had curly ears.
You have to assume that this is complete dominance and one of these traits is dominant. To get the recessive characteristic, the alleles (versions of the gene) both have to be recessive (both lower case). But to have the dominant phenotype, either both alleles could be dominant (upper case) or you could have one of each (heterozygous, where you have one upper case and one lower case). 

So there are two possibilities for genotype of the cat with the dominant characteristic. Since you don't know (yet) which it is, just use the letters "E" and "e" and set up the two possible Punnett squares: 



In the first Punnett square, all the offspring have the same genotype, so they would also have the same phenotype. In the second square, you have offspring with two genotypes, one of which would produce the dominant phenotype (Ee) and one of which would produce the recessive phenotype (ee). Since your problem states that all the offspring have the same phenotype, the correct Punnett square is the first one where all the kittens are heterozygous (Ee). Since the dominant allele (E) masks the recessive allele (e), then curly ears has to be the dominant trait, since that's the phenotype of all the kittens.
