5. In his experiments in studying linked genes on fruitflies, why did Thomas Morgan sometimes see recombinant offspring? a. Linked genes always lead to recombinant types of offspring.
b. Crossing over can "unlink" linked genes so that some recombinant types of offspring result.
c. Nondisjunction sometimes occurs which can separate linked genes. d. Linked genes do not assort independently resulting in all parental types of offspring,
e. Chromosome abnormalities like monosomy and trisomy lead to recombinant types.​

-vessels in the chest

the diagnosis of angina pectoris literally means "vessels in the chest"

explanation;

-angina pectoris is the medical term for chest pain or discomfort due to coronary heart disease.it is the chest pain due to an inadequate supply of oxygen to the heart muscle. the pain is typically severe and crushing, and it is characterized by a feeling of pressure and suffocation just behind the breastbone.

agina pectoris is caused by reduced blood flow to your heart muscle. the blood carries oxygen, which the heart muscle needs to survive. when the heart muscle isn't getting enough oxygen, it causes a condition called ischemia
