Autosomal traits are inherited via genes that do NOT determine an individual's sex. Sex-linked traits, however, are inherited via genes that DO determine and individual's sex (X and Y chromosomes). (The use of Punnett squares is the best way to help visualize this difference.) Autosomal traits are passed on from parents to offspring independent of gender, whereas, because sex-linked traits are carried on the X chromosome and NOT the Y chromosome, males (XY (hemizygous)) have a 50% chance of being either recessesive or dominant for the trait . With sex-linked traits, females however have more possible outcomes in terms of dominant/recessive traits because of their two X chromosomes (XX). This means that both Xs may be dominant (homozygous dominant), both Xs may be recessive (homozygous recessesive), or one X may be dominant while the other is recessive (heterozygous- the dominant trait would be physically represendted). Some examples of autosomal traits are ability/inabilitiy to roll toungue, freckles/no freckles, widows peak/continuous hairline, etc. Two examples of sex-linked traits are Colorblindness and Hemophilia.

What is the Difference between a mutant and mutation?
A mutagen is a substance that CAUSES a mutation. Essentially, mutagens are the cause, mutations are the effect. Simple as that :)
Is it true that a defective allele always recessive and a normal allele always dominant?
No, a defective allele is not always recessive, and a normal allele is not always dominant. The relationship between alleles can be more complex and dependent on specific genetic mechanisms. Dominance and recessiveness are general terms used to describe the relationship between two alleles at a specific gene locus.
What are the similarities of a nonsense mutation and a missense mutation?
Both nonsense and missense mutations are point mutations - meaning a single base has been substituted. The difference between the two is that a missense mutation results in an amino acid being replaced with a different amino acid, whereas a nonsense mutation results in a premature stop codon.
What is the difference between helpful and harmful mutation?
a beneficial mutation in an animal, plant, cell or bacteria will allow it to have a better chance of survival and allow it to continue passing on its DNA in its offspring. a harmful mutation does the exact opposite it hinders the animals survival and will eventually lead it's species to extinction.
What is the difference between a nonsense mutation and a missense mutation?
Missense mutation: changes one sense codon to another, resulting in incorporation of amino acid.Nonsense mutation: changes a sense codon into a stop (or nonsense) codon, resulting in premature termination.
What is the difference between a variation and a mutation?
mutation is an alteration in the nucleotide sequence of a gene whereas variation is any difference between individuals of a particular species.
What is the difference between mutation and variation?
variation is difference between genes and trait among individual* organism within population. mutation is change in genetic instruction I hope it helps
What is a difference between a gene mutation and a chromosomes mutation?
a gene is passed on from generations and a chromosome is just found in certain cells

What is the difference between autosomal and X DNA?
Autosomal DNA is inherited from both parents and is found on the 22 pairs of autosomes. X DNA is inherited from both parents but is found only on the X chromosome.
What is the difference between sex chromosome an autosomal chromosome?
the autosome do not control the sex organs . but the sex chromosome control the sex organs
Is it true that a defective allele always recessive and a normal allele always dominant?
No, a defective allele is not always recessive, and a normal allele is not always dominant. The relationship between alleles can be more complex and dependent on specific genetic mechanisms. Dominance and recessiveness are general terms used to describe the relationship between two alleles at a specific gene locus.
What is the difference between crossover and mutation in genetic algorithm?
mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
Which is not a difference between a population showing exponential growth and a population showing logistic growth?
Mutation Rate
What is one difference between tracing the inheritance of autosomal traits and tracing the inheritance of sex-linked traits?
One key difference is that autosomal traits are located on the autosomes (non-sex chromosomes), while sex-linked traits are located on the sex chromosomes (X or Y). This difference affects how these traits are inherited and expressed, as sex-linked traits show different inheritance patterns among males and females.
What are the similarities of a nonsense mutation and a missense mutation?
Both nonsense and missense mutations are point mutations - meaning a single base has been substituted. The difference between the two is that a missense mutation results in an amino acid being replaced with a different amino acid, whereas a nonsense mutation results in a premature stop codon.
