GENETICS
if your good at athlectics then thank your genetics
WHO DISCOVERED GENETICS
GREGOR MENDELL, he used peas to reprent the traits give from a female pea to male pea.
contrast the follow term: genotype/phenotype
dominant-oberved traits of an organisms thats masked by the dominant form of a trait.recessive -traits of an organisms that can be masked by the dominant form of a trait.heterozygous-when there are two of the sam alleles for trait.(Tt)homozygous-when there are two different alleles for trait.(TT)genotype-combination of genes in an organism.(GG)phenotype-outward appearance of an organism regardless of it genes.(blue eyes)
punnett square
genotype- AA=25% Aa=50% aa=25%
INCOMPLETE DOMINANCE
incomplete dominance is inheritance pattern where the phenotype of a heterozygous is intermediate between those of the two homozygotes. its like crossing a red flower snap dragon plant (RR) with a white flowered snap dragon plant (R'R') all of the F offspring will have pink flower
CODOMINANT
Codominat alleles casue the phenotype of both homozygous to be produced in heterozygous individuals. in codminance, both alleles are expressed equally
MULTIPLE ALLLES
Traits controlled by more than two alleles have multiple alleles and it allows two allelesĀ of a genes can exist within an individual diploid cell.
DESCRIBE SEX-LINKED TRAITS
traits controlled by genes located on sex chromosomes are sex-linked traits. its like fruit fly
