A mother has one allele for color blindness and one allele for nomal vision what is the probability that her gamete will have the allele for color blindness?

Color Blindness is x-linked recessive. Therefore, it could not be heterozygous; the daughter would not be colorblind, but rather have normal vision.

Why deos A mother has one allele for dimples and one allele for no dimples What is the probability that she produces a gamete with the allele for dimples?
Answer is 50% :: Apex
The gamete that contains genes contributed only by the mother?
The egg is the gamete produced by the female.
The gamete that contains genes contributed only by the mother is?
egg
If a mans father has a BBkk genotype for two particular genes and his mother has the BBkk genotype what will the mans genotype be?
BBkk as there is no other alleles present for the man to inherit. the father can only pass on a B allele and a k allele and the mother can also only pass on a B allele and a k allele.
What does an egg contribute to an embryo?
It is the mother's gamete. It contains the 23 chromosomes that she provides to the embryo.

What is the probability that certain genotypes and phenotypes will occur?
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
Color blindness is a recessive trait. The gene for color blindness is on the X-chromosome. The family tree below shows the trait of color blindness. The only unknown is the mother in the first generation?
(Apex Learning) She has at least one recessive color blindness allele.
What process causes gametes to have only one allele?
In sexual reproduction each parent contributes only one allele to the offspring. This is why meiosis takes diploid cells and makes them haploid. The process meiosis separates the homologous pairs, separating the alleles from each other. Thus, each gamete produced has only one allele for each trait. When the male gamete (sperm) fuses with the female gamete (egg) and fertilization takes place, the resulting zygote has two alleles; one from the father and one from the mother.
Why is a son who receives the allele for color blindness from his mother always colorblind?
Being Colorblind means you recieved 2 recessive alleles from you parents. So that means the mother and father must of had 2 recessive alleles. Also Colorblindness is more common in males.
The gamete that contains genes contributed only by the mother?
The egg is the gamete produced by the female.
The gamete that contains genes contributed only by the mother is?
egg
What is probabilaty and how is it used in genetics?
Probabilaty, is actually spelled Probability. Probability is a number to be used to determine a chance of any occasion, such as a Coin-toss, with the probability being %50 of landing on heads/tails. Probability is used in genetics to determine the chance of a offspring having a mother(or father)'s trait. It is used with Punnet squares to determine the chance of a offspring having a parent's trait or allele combination.
If a mans father has a BBkk genotype for two particular genes and his mother has the BBkk genotype what will the mans genotype be?
BBkk as there is no other alleles present for the man to inherit. the father can only pass on a B allele and a k allele and the mother can also only pass on a B allele and a k allele.
What is am example of a dominant allele?
A dominant allele is the allele which expresses itself morphologically.for example;the dimple on your cheek.your mom has a dimple whereas your father doesn't have it .but you too possess it.then ,your mother's allele serves to be the dominant allele.
