If two parents are both blood type B and they have three type B offspring and one type O offspring determine the genotypes of the parents whether they are heterozygous or homozygous?

They must both be OB (heterozygous). * OB produces B type * BB produces B type * OO produces O type We project that 1/4 of offspring will be BB, 1/2 will be OB, and 1/4 will be OO. Since BB and OB have the same phenotype (blood type B), statistically 3/4 will be type B and 1/4 will be type O.

∙ 10y agoWe are looking for the possible blood types of a baby.
Parental information:
- Mother type B --can be BB or BO = contributes B or O gene
- Father type O --can only be OO = contributes the O gene
- Baby is type BO = Type B
- Baby is type OO = Type O
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the Type O parent has the inhibitory gene affecting his Type A or AB,then a Type A baby is definitely possible.

What can you predict about the offspring if you know the genotypes of the parents?
So, if one parent is Aa (heterozygous) and the other parent is aa (homozygous recessive) the punnett square would look like this: ___|_A__|__a_ _a_|_Aa_|_aa_ _a_|_Aa_|_aa_ The genotypes of the offspring 50% heterozygous and 50% homozygous recessive
What phenotype is produce by each of the following genotypes?
The genotype each offspring has is determined by the parents. They can be both homozygous dominant or are they heterozygous and homozygous(dominant or recessive)
What is the probability of offspring for 2 heterozygous dogs?
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
Assuming there is no co-dominance or partial dominance, the result would be that 100% of the offspring would be blue, heterozygous flowers with the phenotype Bb.
If dad has freckles and is homozygous and mom has freckles and is heterozygous what phenotypes and genotypes can you expect their offspring?
Alright, I suppose I will do your homework for you.. Here is your punnet square: F F F FF FF f Ff ff Therefore, 3/4, or 75%, offspring will have the phenotype of having freckles, and 1/4, or 25% will have the phenotype of no freckles. And 2/4, or 50%, of the offspring will have the genotype for homozygous for freckles, 1/4, or 25%, of the offspring will carry a heterozygous trait for freckles, and 1/4, or 25%, of the offspring will have the phenotype for homozygous no freckles.
What crosses will only produce heterozygous offspring?
There only certain crosses that will produce heterozygous offspring. These are heterozygous vs heterozygous, homozygous vs homozygous and heterozygous vs homozygous.

What percentage of genotypes would most likely be found in the f1 generation offspring?
If the parent generation consisted of a homozygous dominant parent and a homozygous recessive parent, then the F1 generation would be 100% heterozygous.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
Assuming there is no co-dominance or partial dominance, the result would be that 100% of the offspring would be blue, heterozygous flowers with the phenotype Bb.
How would you determine the genotype of an individual if it is heterozygous for a character?
You can perform test crosses with individuals of known genotypes and analyse the offspring you get.
What is the probability of 2 heterozygous individuals producing a heterozygous recessive offspring?
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
How do two heterozygous organisms produce on offspring with a recessive phenotype?
There are two forms of Homozygous inheritance: Homozygous Dominant, and Homozygous Recessive. In order for two parents that are Homozygous to produce a Heterozygous offspring, one of them MUST be Homozygous Dominant, and the other MUST be Homozygous Recessive.

What is the probability of a heterhomozygous offspring?
Impossible. You can only be heterozygous or homozygous, not both.
What is the offspring if you cross two heterozygous Tt tall plants?
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
