intermediate phenotype

Sickle cell is what type

of dominance?

What are dominant-recessive

inheritance

equally expressed by both alleles

(Ia, Ib)

alleles at a single locus may have effects on two or more traits

(one alleles having effect on lots of stuff)

discrete variation

(earlobes, height, weight, eye color

genetic disorders)

environmentally produced phenotypes that mimic conditions caused by genetic mutations

(a copy of the way they look, caused by environment)

cells has no defects, the embryo

is implanted in the uterus

manipulating the genetic

makeup of cells or organisms

take dna apart, and recombines

it in new ways, producing new

molecules of dna

cells from the patient's body

or bone marrow are removed

and grown in the lab, exposed

to virus that is carrying the

desired gene, are then returned

to the patient by injection into a vein.

often viruses, or liposome

(fatty particles) are used to

deliver the desired gene to

cells in the patient's body
