A female that is homozygous for an X-linked dominant trait is expected to pass on the trait to what proportion of her children?

She  has a 50% chance of passing the gene to her likeable sons and daughters in equal proportions of 50-50% assuming the inheritance is based on Mendel's Mono hybrid cross with  each of the sex-linked gene moving into each of the offspring boys and girls.

Assuming the husband is normal . the man will give normal Y-chromosomes and the mother will give  either of defective allele(XX), so the  boys,  will all be sex-linked for the traits. Since boys sex genotypes are XY, XY However.the girls will be carrier.

if the man also has  the trait (defective X , but free Y, then) , all the girls will have the sex linked -traits, and be dominant for sex-linked allele like the mother.  since two defective sex-linked traits of XX( one from the father, and one from the mother will be inherited    will be inherited.

Explanation:

The correct answer is - b. highest, lowest.

The supplier of goods (in this case the cookies) always tends to maximize the profit, thus looks for ways to increase the prize as much as possible, while still keeping the good attractive for the consumers.

The consumers, on the other hand, tend to demand goods for prices as lower as possible, while still getting the same quality of the goods.

Naturally, the both perspectives and actions balance themselves, with the end result being a price equilibrium, where the price will be good enough for both sides, though the tendencies for the primary goals will continue.
