How does a geneticists use pedigrees?

genes from one organism are tranferred into the DNA of another organism.

An organism's full set of DNA

an organism that has exactly the same genes as the organism from which it was produced

caused by a mutation that affects the hemoglobin, cannot carry as much oxygen.

involves crossing two individuals that have similar desirable characteristics

What is a genome

process of selecting organisms with desired traits to be parents of the next generation

a person's blood clots very slowly or not at all - cause by a recessive allele on the X chromosome

a chart or "family tree" that tracks which members of a family have a particular trait

an abnormal condition that a person inherits through genes or chromosomes.

the body produces abnormally thick mucus in the lungs and intestines - occurs when two mutated cells are inherited.

Sex-linked genes are genes on
