If a mans father has a BBkk genotype for two particular genes and his mother has the BBkk genotype what will the mans genotype be?
BBkk as there is no other alleles present for the man to inherit. the father can only pass on a B allele and a k allele and the mother can also only pass on a B allele and a k allele.
What word describes an organism that has the genotype Bb?
The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.
What gametes can be formed by an individual with the genotype Aa?
Half of the gametes will contain the A allele, and half will contain the a allele.
Which is the FALSE statement a Phenotype determines genotype b Combination of alleles are known as genotype c A gamete will only receive one allele or another from a pair?
A. Because it goes like this: Phenotype = Genotype + developement.
What is an example of allele?
an allele is an alternative form of a gene that governs a characteristic, like hair or eye color. an individual gets 1 allele for each charecteristic from each parent. There are dominant alleles and recessive alleles. The dominant allele is the allele that is the person's physical appearance, and the recessive allele is the one that isn't visible but the person has in his/her genotype.

If the allele B represents black fur and the allele b represents white fur what would be the genotype of an animal with white fur?
White fur
What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
Baby Y has parents with AB and A blood types have a daughter with type A blood, what is baby Y’s genotype?
The blood type A is determined by having either two A alleles (genotype AA) or one A and one O allele (genotype AO). In this case, since the parents have blood types AB and A, they can only pass on an A allele or a B allele to their child. If the parents have a daughter with blood type A, it means they both contributed an A allele, as the daughter cannot have a B allele since her blood type is A. So, the genotype of the daughter is AO. Now, if we consider Baby Y, we can infer that Baby Y could inherit one A allele from one parent (let's say from the parent with blood type A) and one A allele or one B allele from the other parent (the parent with blood type AB). Therefore, Baby Y's genotype could be either AA or AB.
What gametes can be formed by an individual with the genotype Aa?
Half of the gametes will contain the A allele, and half will contain the a allele.
What gamete can be made of BB?
A gamete containing a BB genotype will carry one B allele from each parent. This gamete will contribute one B allele to offspring during fertilization.
In the individual with genotype AaBB what percentage of gametes will contain the A allele?
You need to make a Punnet Square Put A and a on top and B and B on the left side. These represent the possible gametes. Your results should be: AB AB Ba (aB) Ba (aB) So 50% of the genotype have the A allele.
Which is the FALSE statement a Phenotype determines genotype b Combination of alleles are known as genotype c A gamete will only receive one allele or another from a pair?
A. Because it goes like this: Phenotype = Genotype + developement.
How do you find the possible genotypes of the children of a woman with blood type O and a man with blood type AB?
There are three alleles for blood type which can be represented by IA, IB, and i. A person with blood type O has the genotype ii. A person with blood type AB has genotype IAIB. If these two people produce children, those children will inherit one allele from each parent. They will therefore certainly inherit the i allele from their mother and either the IA or the IB from their father. The children with the genotype IAi will have type A blood, since the IA allele is dominant to the i allele. The children with the genotype IBi will have type B blood, since the IB allele is also dominant to the i allele.
Why do a man with AB blood and a female with A blood have a offspring with B blood?
The female would have to have the blood genotype of AO. The recessive O is masked by the female with the domaint A allele. Their offsprings genotype would be BO the B would be from the father and the recessive O from the mother.
Why does natural selection act on phenotype rather than genotype of an organism?
This seems to be an odd question to ask... Unless I'm mistaken, the phenotype of a given organism is governed by its genotype, and changed a fair amount by the organism's environment. Consider the following circumstances: Organism A has a long set of arms, and has a "long arm" allele. Organism B has short arms and a "short arm" allele. For example, A's genotype has the "long arm" allele, and seen in its phenotype it has long arms. The converse is true for B. Judging by your usage of technical terms in your question, I'm sure I don't need to tell you that A will out-compete B, assuming they are in a food-is-up-high environment. So, A will end up with more offspring than B, again assuming that A and B are members of different species. Eventually organism A will become prevalent, and natural selection will have caused there to be more organisms with the "long arms" phenotype, and the "long arm" allele in their genotype. In summation, Genotype governs Phenotype, and the best geno- and phenotypes will be chosen by natural selection. By an organism having a superior phenotype, it also has a superior genotype.
