Frequent question: What is the genotype of a person with type O blood?

Someone with blood type O has neither the A nor the B allele. The genotype must be OO.

What is the genotype of a person with type O blood quizlet?

Someone with blood type O has neither the A nor the B allele . This genotype must be OO.

What makes a person type O blood?

Group O: The plasma contains both anti-A and anti-B antibodies, but the surface of the red blood cells does not contain any A or B antigens. Since these antigens are not present, a person with any ABO blood type can receive this type of blood.

What genotypes will lead to blood group O phenotype quizlet?

A and B alleles are dominant over O. AO genotype will have an A phenotype. OO genotypes will have an O phenotype (inherited a recessive O allele from both parents).

What is Betsy’s genotype for her blood type?

Genotype of Betsy’s for her blood group is IAi I A i or A. She is heterozygous for the A blood group. Bob’s genotype for his blood group is IBi I B i or B. He is heterozygous for the B blood group.

What is special about O positive?

Type O positive blood is given to patients more than any other blood type, which is why it’s considered the most needed blood type. … Type O positive blood is critical in trauma care. Those with O positive blood can only receive transfusions from O positive or O negative blood types.

What is the newest blood type?

Researchers at the University of Vermont have made a discovery that could save the lives of thousands of people. They’ve identified two new blood types called Langereis and Junior.

Is the phenotype always reflective of genotype in blood type?

The sum of an organism’s observable characteristics is their phenotype. … Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.

Which of the following genotypes is homozygous?

A homozygous genotype means that you have two of the same alleles, which are represented by the letters A or a. So if an individual has AA or aa, we say they are homozygous.

Which of the following genotypes is a heterozygote?

The correct answer: Among the following genotypes the heterozygous genotypes are: 3. Aa and 4.

How many genotypes are there for the ABO blood type?

The ABO blood group antigens are encoded by one genetic locus, the ABO locus, which has three alternative (allelic) forms—A, B, and O. A child receives one of the three alleles from each parent, giving rise to six possible genotypes and four possible blood types (phenotypes).

What is incomplete dominant?

Abstract. Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance. Mendel described dominance but not incomplete dominance.
