Hybrid, probably. That means it would be unable to reproduce.

How does codominance work and why does it happen?
Incomplete dominance occurs when a homozygous genotype produces an intermediate, or middle phase before the result. This intermediate is the heterozygous' phenotype.
Explain the difference between intermediate inheritance and codominance?
In codominance, neither phenotype is recessive. Instead, the heterozygous individual expresses bothphenotypes. Intermediate inheritance is when neither allele is dominant to another, but a mixture is produced in the 2 alleles present. A mixed phenotype is given that is between the two parents phenotype .e.g Red flowers (RR) crossed with white flowers (WW) produces pink flowers (RW).
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
What is the probability of a man who has BB genotype and his wife who has BO genotype to have a child who is AB?
No probability. Neither parent has an "A" for the child to inherit to make an "AB".
Can a child's genotype be different from that of both parents?
A genotype is decided from two alleles. One of these alleles comes from the father, and one comes from the mother. Thus it should be clear that the genotype can be different from both parents. For instance, suppose the father has genotype AA, and the mother has genotype aa. In this case, the child will have genotype Aa, which neither parent has.
Is todd homozygous or heterozygous for pku?
no neither
When there are two different alleles for a trait?
If you have a heterozygous genotype (X, x), then you would take on the phenotype of the dominant allele. There are some instances where neither trait is fully dominant over the other. This is called incomplete dominance, and usually results in a blending effect of the two traits.
A child is born with type AB blood what blood must the parents have?
The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents. If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A. If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
Do heterozygous and homozygous result in the same phenotype for blood groups?
Yes. Whether you are heterozygous or homozygous only matters in parenting, to know the possibilities of your offspring. However, the only recessive trait in the blood is type O. The other two genes, A and B, are co-dominant, meaning if you have one of each, you'll have AB blood, because neither is dominant to the other.
How is a snap dragon an example of incomplete dominance?
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
What is it when alleles are neither dominant or recessive?
It is called CODOMINANCE if the alleles each express when the phenotype is heterozygous. Let's look at the following situation. There are snapdragon flowers that are homozygous (having 2 of the same allele) for red. Let's call them R. There are also snapdragon flowers that are homozygous for white. Let's call them r. If you take one of the RR flowers and breed it with a rr flower, you will get Rr. If one of the alleles is dominant, then the flower will be the color of the dominant allele. If R (red) is the dominant allele, then all of the offspring will be red; if r (white) is the dominant allele, then they will be white. However, if they are codominant, then if the genotype is heterozygous (Rr), then the alleles will both express- in this case, the offspring would be pink. Hope I helped!
What is the probability of a homozygous recessive offspring?
It depends. If it's a heterozygous cross, (Tt x Tt), there's a 25% chance. If it's a homozygous dominant cross (TT x TT), the chance is 0%. Neither parent has the alleles for a recessive trait, so none of their offspring can have the recessive trait. If it's a homozygous recessive cross (tt x tt), there's a 100% chance. The only alleles the parents can pass on are recessive.
