what is the study of genetics?

it is the study of heredity.

who discovered genetics and how did he do this?

gregor mendal, and he did this by pea plants. He wrote down when there offsprings came out tall or short. And when they came in dominant they were tall. But if they were short they were recessive.

contrast the following terms: dominant/recessive alleles

DOMINANT      1. eye color- brown      2. vision- farsightedness      3. hair- dark hair RECESSIVE      1. eye color- grey, green, haze, blue      2. vision- normal, nearsighted, night blindness      3. Hair- blonde, light, light red

50% phenotype.50% genotype. 

incomplete dominance and provide an example.

incomplete dominance- is a type of inheritance in which one allele for a specific trait is not completely dominant over the other allele. in other words one goes on top and the other on the bottom.

codominance and provide an example

In genetics, codominance is a phenomenon in which a single gene has more than one dominant allele.

Multiple alleles and what are they used to determine

An allele, or allel, is one of a number of alternative forms of the same gene or same genetic locus.

Sex linked traits

Sex linkage is the phenotypic expression of an allele related to the chromosomal sex of the individual.
