genetic info

Whats mitosis? cell divisoin
Whats a chromosome? threadlike gene carrier
whats meiosis? sex cell division
Whats DNA? deoxyribonucleic acid; transfers genetic characteristics
Whats a mutation? any change from normal
Whats a recessive trait? the trait thats coverd by the dominant
Whats a dominant trait? Covers the recessive
who was mendel? austrian who founded the science of genetics
whats a pedigree? table/chart of genes
Whats co-dominance? 2 different alleles that are both heterozygous
What are sex linked traits? trait that only males or only females would have
Whats homozygous? an organism whose two alleles for a trait are exactly the same
Whats a heterozygous? an organism with two dif. alleles for a trait
What does the prefix poly stand for in genetics? a type of inheritance where more than one gene controls a trait
What determines the traits? the alleles on the chromosomes
What are the two allele forms? dominant and recessive
What happens in meiosis? the chromosomes seperate and the allels go in seperate sex cells
Whats an example of a polygenic inheritance? eye color
what is a type of genetic disorder? diabetes, whenyou dont have enough insulin in your body
Whats genetic engineering? When scientists change the arrangement of DNA.
Whats an example of genetic engineering? Gene therapy
HOw could two parents with Type A and type B blood have a baby that has type O? The O blood type could be recessive and both the parents have those alleles. (AO and BO)
what role do genes play? they control the traits that show up in organisms
What 3 principles of heredity did Mendel discover? 1. traits are controlled by alleles on chromosomes. 2. an allele may be dominant or recessive in action. 3. when a pair of chromosomes seperate the alleles go into seperate sex cells
Whats heredity? the passing of traits from one generation to antoher
Whats incomplete dominance? both allels are expressed in offspring
Whats a hybrid? recieves dif. genetic info from each parent; same as heterozygous
whats a dominant trait? trait that covers up the recessive
Whats a punnett square? a tool used to predict the possible offspring of a mating
whats genotype? the genetic makeup of an organism
whats genetics? the study of how traits are inherited through the interactions of alleles
