Are the parents of a albino plant homozygous or heterozygous?
The parents of an albino plant are likely to be heterozygous for the gene controlling albinism. This means they carry one normal allele and one albino allele. When these two alleles combine in the offspring, it results in the expression of the albino trait.
A male and female bison that are both heterozygous for normal skin pigmentation produce an albino offspring Which of Mendels principles explain why the offspring is albino?
Both parents would each have one dominant gene for normal pigmintation and each would have one recessive albino gene. Say P is the dominant gene and q is the albino gene. Then the parents genotype would both be Pq. Below is a Punnet Square. The child's genotype is qq P q ------------------------------------- P / PP / Pq (carrier) / / / / ///////////////////////////////////////// q / Pq (carrier) / qq (albino) / / / / ////////////////////////////////////////
When an allele mask the presence of another allele it is said to be?
Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A). One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color. If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.
The photo below shows an albino offspring from a non-albino mother. If albinism is a recessive trait, what are the possible genotypes of the mother, the father, and the offspring?
For the mother to have a non-albino offspring, she would need to have at least one dominant allele for the trait, so her genotype could be either Aa or AA. The father must have two recessive alleles (aa) to pass on albinism to the offspring. The albino offspring's genotype would be aa.
Can two white people have an albino baby?
Albinism is a recessive trait, meaning that an albino person has the genotype AA, while a person who isn't albino has the trait Aa or AA. Two albino people (AA x AA) will have all albino children. Aa x AA will have a 50% probability of albino children, and 50% normal children who are carriers (Aa). AA x AA will have all normal children who are carriers (Aa). Aa x Aa will have 25% AA (normal/non carriers), 25% AA (albino), and 50% Aa (normal/carriers) offspring. AA x AA will have all normal children who are not carriers (AA).*A person who has the genotype Aa is a carrier because they carry the allele (a) for albinism but they are not albino. The allele (A) is dominant so it covers the (a) allele.

A cross between two albino people can result in how many albino of spring?
Albinism comes from recessive alleles, so 100% of the children will be albino if both parents are. On the rare event of a germline mutation in this allele in the parents' gametes, there may be a non albino child. Some animals are now entirely albino, google "blind cave tetra".
If a allele is masked is it recessive?
If an allele is masked, it is most likely recessive, but not necessarily. This is due to epistasis, the interaction between two or more genes to control a single phenotype. For example, "K" codes for more keratin pigment in the skin, but "k" does not. One can still be albino, however, for if they get the dominant "A" allele, this allelle will override and mask the dominant "K" pigment in the skin, making the person albino.

What colors will the offspring of a black cat carrying a white allele and a purebred white cat be?
There is no such thing as a "purebred" white cat. White and black are just colours, not breeds. For a start, there are two genes that can make a cat white: The usual being dominant and therefore cannot be carried by a black cat, and the recessive albino. My guess is we are only talking about the recessive allele, so we have a black cat carrying albino (Cc) and a pure albino (cc). In this case half the kittens would be white (cc) and half would be black (Cc). Forgetting the albino gene, the black cat would not be carrying white at all (ww), the pure white cat would be dominant (WW), and all the offspring would be white (Ww). In life I would say the purewhite cat is most likely dominant and if the black cat carries the albino allele or not it makes no difference; all offspring would be white.

The number of times an allele occurs in a gene pool?
The frequency of an allele in a gene pool is determined by counting the number of copies of that allele in a population. This frequency can change through evolutionary processes such as genetic drift, natural selection, mutation, and gene flow. Tracking allele frequencies helps scientists study population genetics and evolutionary dynamics.
