Michelle was curious about her mother's blood type. Michelle knew that her own blood type was o,
her father's blood type was A, and her two sisters and one brother both also had type A blood. How
could Michelle have type o when everyone else around her seems to have type A blood? Michelle is
really frustrated. Please help her out by making a possible Punnett square showing how this could
happen.
Answers
Blood type is determined by the I gene. IAIA and IAi determines A blood type. IBIB and IBi determines B blood type. ii determines 0 blood type. Michelle's mother must at least carry one recessive allele i.
--------------------------------
The blood type is determined by a gene, which is triallelic.
IA dominant over i. The person presents A type of antigens.IB dominant over i. The person presents B type of antigens.IA and IB are codominant. The person presents both types of antigens, A and B.i is the recessive allele. The person does not present any antigen.⇒ H0m0zyg0us dominant individuals IAIA, or heter0zyg0us Individuals IAi, will express the A blood type.
⇒ H0m0zyg0us dominant individuals IBIB, or heter0zyg0us Individuals IBi, will express the B blood type.
⇒ Individuals with h0m0zyg0us recessive genotype, ii will express the 0 blood type.
⇒ Individuals carrying IA and IB alleles will express the AB blood type.
To solve the problem, we will use this information.
We know that
Michelle is blood type 0 Father is blood type ABrother and sister are blood type AMother??⇒ If Michelle is blood type 0, then her genotype is ii. She must have received one recessive allele from her father and one from her mother.
⇒ This suggests that Michelle's father, who is blood type A, is heter0zyg0us IAi. He must have at least one dominant allele IA that determines his phenotype, and one i allele.
⇒ Michelle's brother and sisters are also type A. They might be either h0m0zyg0us dominant IAIA or heter0zyg0us IAi.
⇒ Michelle's mother should have at least one recessive allele i. She could be either IAi or IBi, or ii. There are three possible option for her genotype.
Let us make the Punnet squares to understand it better. We know the genotype of the father, but there are three options for the mother.
Option 1
Cross) father x mother
Parentals) IAi x IAi
Gametes) IA i IA i
Punnett square) IA i
IA IAIA IAi
i IAi ii
F1) 25% of the progeny is expected to be h0m0zyg0us dominant IAIA
50% of the progeny is expected to be heter0zygus IAi
25% of the progeny is expected to be h0m0zyg0us recessive ii
75% of the progeny is expected to be blood type A ⇒ IAIA and IAi ⇒ Sisters and brother
25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle
Option 2
Cross) father x mother
Parentals) IAi x IBi
Gametes) IA i IB i
Punnett square) IA i
IB IBIA IBi
i IAi ii
F1) 25% of the progeny is expected to be IAIB
25% of the progeny is expected to be heter0zygus IAi
25% of the progeny is expected to be heter0zygus IBi
25% of the progeny is expected to be h0m0zyg0us recessive ii
25% of the progeny is expected to be blood type AB ⇒ IAIB
25% of the progeny is expected to be blood type A ⇒ IAi ⇒ Sisters and brother
25% of the progeny is expected to be blood type B ⇒ IBi
25% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle
Option 3
Cross) father x mother
Parentals) IAi x ii
Gametes) IA i i i
Punnett square) IA i
i IAi ii
i IAi ii
F1) 50% of the progeny is expected to be heter0zygus IAi
25% of the progeny is expected to be h0m0zyg0us recessive ii
50% of the progeny is expected to be blood type A ⇒ IAi ⇒ Sisters and brother
50% of the progeny is expected to be blood tye 0 ⇒ ii ⇒ Michelle
Despite the fact we can not determine for sure the mother's genotype, we know that she carries at least one recessive allele, which is why Michelle's blood type is 0.

Hemophilia is a disorder in which there is a failure in one of the steps of clot formation.What might be some advantages and disadvantages of this disorder?
Answers
People who have severe hemophilia may benefit from regular injections of clotting factors as a preventive treatment. This may lower the risk of severe bleeding. Severe hemophilia affects the blood's clotting ability so much that people who have it may start bleeding for no apparent reason.
Hemophilia can result in: Bleeding within joints that can lead to chronic joint disease and pain. Bleeding in the head and sometimes in the brain which can cause long term problems, such as seizures and paralysis. Death can occur if the bleeding cannot be stopped or if it occurs in a vital organ such as the brain. Complications of hemophilia can include: Deep internal bleeding. Bleeding that occurs in deep muscle can cause the limbs to swell. The swelling can press on nerves and lead to numbness or pain.

which best represents an example of carbon fixation?
Answers
The option that best represents an example of carbon fixation would be the incorporation of CO2 into organic molecules.
Carbon fixation refers to the process of converting atmospheric carbon, mostly in the form of carbon dioxide, to organic molecules in the form of carbohydrates, usually in living organisms.
In living organisms carbon is fixed either via photosynthesis or chemosynthesis.
During the photosynthetic process, inorganic carbon in the form of carbon dioxide combines with water and is converted into carbohydrates in the presence of radiant energy. The process usually happens in green plants.
During chemosynthesis, carbon dioxide reacts with H2S instead of water to arrive at carbohydrates. The process usually happens in chemosynthetic bacteria.
More on carbon fixation can be found here: https://brainly.com/question/7142342
The process of photosynthesis is the best example of carbon fixation.
In the process of photosynthesis, energy from sunlight drives the carbon fixation pathway. photosynthesis process is used by the primary producers such as plants, algae, and cyanobacteria. They contain green pigment named chlorophyll that used the Calvin cycle to fix carbon.
The carbon atom present in the atmosphere in the form of carbondioxide gas fixes by the producers in the form of glucose which have 6 carbon atoms so we can conclude that photosynthesis is the best example of carbon fixation.

what organ in the body regulates erythrocyte production?
Answers
Answer:
The hormone erythropoietin regulates enthrocyte production, which is produced in the kidneys.
Explanation:
Bone marrow is the body organ responsible for controlling erythrocyte (red blood cell) synthesis.
The process of erythropoiesis, which occurs largely in the bone marrow, produces erythrocytes. Hematopoietic stem cells, which can differentiate and develop into several types of blood cells, including erythrocytes, are found in the bone marrow.
The hormone erythropoietin (EPO), which is produced and secreted by the kidneys in response to low oxygen levels in the body, regulates the formation and release of erythrocytes. EPO stimulates the formation of erythrocytes in the bone marrow, maintaining an adequate supply of oxygen-carrying red blood cells in the bloodstream.

Answer:
All carbohydrates are made from smaller building blocks known as monosaccharides. Their main function is energy storage. The elements found in carbohydrates include Carbon, Hydrogen, and Oxygen
Explanation:
Carbohydrates are a fundamental organic compound that is essential to life. Their building blocks are known as monosaccharides, these are also known as simple sugars such as glucose. They all follow the same multiple of the unit C6H2O (1 C : 2 H : 1 O). We need to carbohydrates to store energy so that when we consume them we can perform cellular respiration, a highly precise process where we can break down glucose to form ATP for our body.
