Hello!
Hemoglobin is the protein which carries oxygen by binding to it. Hemoglobin is found in red blood cells. This protein is extremely important as it allows respiration to be carried out, and transports oxygen to the rest of our bodies.
Oxygen diffuses from the alveoli (in our lungs) through capillaries into the blood. From there, the hemoglobin in the blood will take the oxygen, and bring it to the other parts of the body which need it. This also allows continued diffusion into the capillaries.
Hope this helps!
Answer:
1/8
Explanation:
Father: normal vision, type A
Mother: normal vision, type A
They can only produce a colourblind son if female is the carrier for it:
XC Xc
XC XCXC XCXc
Y XCY XcY
XcY son will be colorblind. Hence father has XCY genotype and mother has XCXc genotype for vision.
They can only produce type O son if both of them are heterozygous for type A:
A O
A AA AO
O AO OO
OO son will have type O blood. Hence both father and mother have AO genotype for blood type.
Probability of having a female child=1/2
Probability of having a normal vision female child = 1 since in the first punnett square it has been shown that all female children have normal vision ( half are carriers )
Probability of having type O child = 1/4
Probability of having a female child with normal vision and type O blood = 1/2 * 1 * 1/4 = 1/8
