For the following crosses, indicate the probability of obtaining the indicated genotype in an offspring. remember, it is easiest to treat each gene separately as a monohybrid cross and then combine the probabilities.

1. cross: aabb × aabb
offspring: aabb
2. cross: aabb × aabb
offspring: aabb
3. cross: aabbcc × aabbcc
offspring: aabbcc
4. cross: aabbcc × aabbcc
offspring: aabbcc

1. Frequency of Aabb= 1/8

2. Frequency of aaBB= 1/16

3. Frequency of  AaBbCc = 1/2

4. Frequency of aabbcc = 1/32

Explanation:

1. Cross: AABb × AaBb

Offspring: Aabb

AA x Aa= 1/2 AA: 1/2 Aa

Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb

Frequency of Aabb= 1/2 Aa x 1/4 bb= 1/8

2. Cross: AaBb × AaBb

Offspring: aaBB

Aa x Aa= 1/4 Aa: 1/2 Aa: 1/4 aa

Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb

Frequency of aaBB= 1/4 aa x 1/4 BB= 1/16

3. Cross: AABbcc × aabbCC

Offspring: AaBbCc

AA x aa = All Aa

Bb x bb = 1/2 Bb : 1/2 bb

cc x CC = All Cc

Frequency of  AaBbCc  = 1 Aa x 1/2 Bb: 1 Cc = 1/2

4. Cross: AaBbCc × AaBbcc

Offspring: aabbcc

Aa x Aa= 1/4 Aa: 1/2 Aa: 1/4 aa

Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb

Cc x cc = 1/2 Cc: 1/2 cc

Frequency of aabbcc = 1/4 aa x 1/4 bb x 1/2 cc= 1/32

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
