How can 2 people with type B blood have a child with type O blood?
So two B parents can make an O child if both parents are BO. How? By each of them passing down their O version. If mom passes her O and so does dad, then the child will be OO which is O type blood.
What is O+ in genotype?
O+ simply means that your red blood cell do jot have either antigen A or B on its surface, and the red cells are also positive to the rhesus factors. However, it should be noted that a person with a blood group of O- is known as a Universal Donor.
How do Genetics determine blood type?
Blood Inheritance Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.
Is A or B blood type dominant?
Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.
CAN A+ and O have a baby?
Could you please explain if it is possible for a father who has O positive blood and a mother with A positive blood to have a baby with O negative blood? I am a little confused and have been trying to research the answer. I would appreciate if you are able to assist. Yes this is definitely possible.
Can 2 O positive parents have a baby?
Theoretically yes, but it would be extremely rare. Two O parents will get an O child nearly all of the time.
Can O+ have AA genotype?
Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles….Blood types and genotypes?
| Blood type | Possible genotypes |
|---|---|
| O | OO |
What is BB genotype?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB. An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype.
What is the genotype in a Punnett square?
Monohybrid Cross. -Dominant genes are expressed over recessive genes.…
How does a Punnett square show genotype and phenotype?
The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. A genotype is the genetic makeup of the organism. This is shown by the three genetic conditions described earlier (BB, Bb, bb). The phenotype is the trait those genes express.
What are the outcomes for a punnet square?
Understand genes and genotypes. A genotype is the heritable,genetic code of an individual.
What are the letters in punnet squares called?
