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.

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) / / / / ////////////////////////////////////////
What cross could Morgan have performed to make the first white-eyed female fruit fly?
A Heterozygous female with a white eyed male.
What is the pattern of sex linked inheritance?
In humans sex linked traits are passed on the X chromosome. (For the purpose of this discussion the trait being passed is recessive.) This means that a male parent cannot pass the characteristic on to his male offspring, but he can pass the trait on to his female offspring. The female parent can pass the trait on to any of her offspring. Both parents must carry the allele for the sex-linked trait (and pass it on) in order for a female child to have the characteristic. Male children that get the trait from their mother will have the trait no matter what the genetics of the father. If the female parent is heterozygous for the trait 50% of her male children will have the characteristic no matter the father's genetics for that trait. Assuming that the characteristic is not lethal and both parents are "carriers" (keep in mind that the father displays the trait and a heterozygous mother will not)... 50% of the sons will have the trait, 50% of the sons will not have the trait, 50% of the daughters will be homozygous for the trait and 50% will by heterozygous "carriers".
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotypic ratio is a 3:1 ratio.
If a female fruit fly heterozygous for red eyes crossed with a white eyed male what percent of their offspring would have white eyes?
50%

What percentage of children have progeria?
What are the chances of a person with this disease passing the disease to their offspring (include possible scenarios)?Scenarios:Full Albino and Full Albino have a 100% chance of having an Albino child.If both parents with albinism have the same type of albinism (i.e. OCA1, then the children will be affected), However if both parents have different types of albinism the children will be normally pigmented and carriers for both defective genes. (Leigh Lauflin)Full Albino and Normal person have a 50% chance of an albino child and a 50% chance of a carrier, but normal child.A heterozygous albino male and a carrier female have a 75% chance of getting an albino or carrier child and a 25% chance of getting a normal child.

In humans widow's peak (W) is dominant over straight hairline (w). If a heterozygous male marries a female with a straight hairline what percent of their children can be expected to have widow's peak?
50% of their children are expected to have a widow's peak. When a heterozygous male (Ww) with a widow's peak gene marries a female with a straight hairline (ww), their offspring have a 50% chance of inheriting the widow's peak gene from the father.

What turtles do you breed to make albino red eared sliders?
You breed a male and female Red Eared slider. Albino's are not different species of turtles, they are just a different version of that specie, but I am breeding turtles as well and you can also have an albino map turtle and so on and on...
Can a golden hamster be with a female albino hamster and make babies?
'Golden' hamster is an alternate name for a Syrian Hamster. Assuming the albino female is too a Syrian Hamster, then yes, they can mate. If it's some variety of dwarf hamster, then no.
Why can a female be a carrier of a sex linked genetic disorder?
When a female is heterozygous i.e. she possess one allele of disease , she is called carrier .
