In this scenario, the mother is heterozygous for normal skin pigmentation (Aa) and the father is homozygous recessive for albinism (aa). The possible genotypes for their child are Aa (normal pigmentation) and aa (albino). Using a Punnett square, there is a 50% probability that the child will be albino (aa).
Albinism is a recessive trait which will result in a lack of pigmentation in the skin eyes and hair. It occurs about 1 in every 17,000 people in the U.S.
genetically albinism is an autosomal recessive gene which in fact gives the child a 25% chance of inheriting the gene if both parents are carriers
Albinism is a recessive trait.
Albinism is typically caused by a recessive gene.
An Autosomal recessive pattern is one in which certain genes of the X sex chromosome are turned off, autosomal is in reference to the X chromosome and the fact that the genes are turned off is indicated by the recessive. So in the case of Albinism the pigmentation genes in the X chromosome are turned off causing the various side effects.
because the recessive allele is still present in heterozygous individuals. these individuals have one dominant allele and so show the dominant phenotype but they are capable of producing offspring with the recessive condition
I think no. It's caused by a recessive gene so if a person has albinism their genotype can only be recessive, recessive ---> AA (small a small a or whatever you call it). No other genotype will mean that person has Albinism, like if it has at least one big A, that means it's just a carrier of albinism.

Recessive allele.
Albinism is a recessive, autosomal trait. So no, it is not sex-linked.
White tigers are those who inherit a recessive gene, one that causes partial albinism. (White animals, those lacking normal pigmentation, are called albinos).
The chance that their next child will have normal pigmentation is 75%. Albinism is usually caused by a recessive gene, so both parents would need to carry the gene in order to have an albino child. If both parents have normal pigmentation, then the chance of passing on the albino gene to their next child is 25%.
