If red eyes are dominant, then 75% will have red eyes and 25% will have white eyes. The genetic breakdown is: 25% will be RR (homozygous red eyes), 50% will be Rr (heterozygous red eyes) and 25% will be rr (homozygous white eyes).

A young offspring of a doe (female deer) is called a fawn.
No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female. The sperm have either an x chromosone or a y chromosone which carries the male sex determination. It is by chance and timing which one fertilized the egg first. If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female.

It is found in both male and female chromosomes.....found in answer key
The resulting offspring will have 50% chance of having straight toes and being heterozygous, and 50% chance of having curled toes and being recessive.

you have a 1:3 chance of the offspring having white eyes
The male reproductive system produces and delivers sperm. This is what fertilizes the eggs from the female, resulting in offspring.
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".
The combination of a female offspring would be XX

They are the offspring of female horses and male donkeys.
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.
A mule is the offspring resulting from the mating of a male donkey with a female horse, or mare. When the 'opposite' pairing of the parents' genders occurs; that is, the mating of a male horse, or stallion, with a female donkey, known as a "jenny" the resulting offspring is more appropriately referred to as a "hinny". The characteristics of a mule versus a hinny are indeed different, as is found in other crossbred animals where the parents' gender has such an effect with one notable example being the difference between a tigon, or a liger, each the offspring of a tiger and lion pair.
A female salmon lays eggs that are fertilized by a male salmon and hatch into a new fish. (study island answer)
