In nature genetically albino plants genotype gg do not survive long enough to produce seeds. Why do you thing some plants still carry the mutant g allele?

It may not be a "mutant" allele but a recessive allele that offers other (perhaps yet-unknown) benefits. Or, it has never caused a significant enough problem to have evolved out of the genome.

What is the genotype of an albino?
An albino has all recessive genes for pigmentation. Hence there is no expression for pigment. In other words the genotype of an albino is homozygous recessive.
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) / / / / ////////////////////////////////////////
An albino individual lacks the ability to produce?
melanin
If a heterozygous male mates with an albino female what percentage of children will be albino?
Albinism is a sex-linked trait. Accordingly, the description of "heterozygous male" doesn't make sense. The sex chromosomes for males are XY, and usually genetic disorders are passed down by the X chromosome (which is the case for albinism). So in the problem, we aren't sure whether the male is XaY or XAY. It would be more helpful to know if the male was albino or not; we would then immediately know his genotype. We can, however, figure out the genotype of the female. Because albinism is recessive, we can deduce that her genotyple is XaXa. But without knowing the male's genotype or phenotype, the offspring percentages cannot be calculated.
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.

How is an albino formed?
Albinism is genetically determined.

Which gene produces albino?
biological inheritance of genetically recessive alleles (genes)
How does a albino snake survive in the wild?
Albino snakes are able to survive in the wild by staying out of sight and doing their best to camouflage into their environments. However, sometimes they are unable to survive in the wild.
Why a person with albino cannot survive?
they can survive like you and I without too many problems
If an albino child is born to two individuals with normal pigment what is the genotype of each parent?
Each parent is heterozygous for the gene.
An albino individual lacks the ability to produce?
melanin
How many offspring does an albino alligator produce?
50 are produced
Albino dog and cat survive in a room 10 minutes?
Mine didn't.
Are there such things as white kangaroos?
Yes, just like many other animals, there can be kangaroos which grow white fur. On occasion, there are even albino kangaroos. This occurs genetically when an animal has no pigment in it's cells, causing the skin and fur to be completely white and the irises in the eye to be red. Albino animals don't survive very long in the wild because their lack or coloring and camoflage makes then very easy targets for predators.
