Only one. The X chromosome is bigger and contains things not on the Y chromosome. So if the only copy men have are the diseased copy, then they will have the color blindness or whatever other disease in question. Since the genes are usually recessive, then females would typically have one good copy that is generally dominant.
There is a theory that in one type of color blindness, the genes are co-dominant. So instead of just the normal 3 types of cone cells in the eye, or the mutated red cones with the rest being normal, the women with both the normal and the mutated genes end up having both the normal and mutated cones, thus having a greater level of color discrimination than normal.

What happens to alleles when gametes form?
When gametes are formed through a process called reproduction, where a male's gamete combines with a female gametes' cell and produces a zygote; the alleles for that are varied in different fertilized zygotes. For example a zygote could have two different alleles from the gene from the male and the female; G and g, thus it would be heterozygous. However at the same time another zygote could have the gene of GG which would be homozygous and pure green.
Why can females but not males be carriers of sexlinked genetic disorders?
Several genetic disorders are caused by genes on the X chromosomes.
Is Gene a male or a female name?
Gene is a male name
How many alleles do your gametes have?
Gametes should contain one allele for each gene locus. This means that gametes will have one allele for each of the genes on the chromosomes they are carrying. It is estimated that humans have about 20,000-30,000 genes - meaning each gamete would therefore have 20,000-30,000 alleles.
Mendel determined that pea plants have two alleles that determine height Where do these alleles come from?
One from Male, and one from Female
How do lions benefit from living in prides?
Since there is only one dominant make in the group (pride), the dominant male would reproduce and pass on its alleles to the next generation. As the alleles of the dominant male is good, the good quality alleles are passed on to the next generation which makes the gene pool stronger.

Can a chocolate and yellow lab have a black puppy?
"Do NOT breed a yellow and a chocolate. You will get what are called "dudleys". They will have no black pigmentation, so a pink nose, pink or yellow eyes, pink paw pads, etc. A chocolate and a yellow are incapable of having a black puppy, as neither carry a dominant black gene. " Whoever said that obviously doesn't know about Labrador genetics. My Chocolate lab and yellow father had 2 black puppies in their litter 4 days ago. There are TWO genes that determine labrador colour. One gene detemines the chocolate/black colour, one gene determines yellow colouring. In the each gene, there two alleles, if you like. Correctly, a chocolate lab can not carry the black gene as it is dominant and the chocolate gene is ressessive. The chocolate dog has to have 2 chocolate alleles. However, the yellow colouring gene is irrespective of the chocolate/black gene. If that gene has two ressessive yellow alleles, the dog WILL be yellow, regardless if it carries 1 or 2 black alleles in the first chocolate/black gene. If you don't yunderstand that, you do not have the knowledge to answer such a question and give people wrong advice. And my Lolas puppies are beautiful, by the way.
Does male carry the A dominate gene?
In humans, the inheritance of many traits, including blood type, is determined by multiple genes. The ABO blood group system is one such example. The ABO system is controlled by three alleles, which are alternative forms of the same gene, on chromosome 9. The three alleles are A, B, and O. Each person has two copies of the ABO gene, one inherited from each parent. The A and B alleles are codominant, meaning that if a person inherits both A and B alleles, they will express both A and B antigens on their red blood cells. The O allele is recessive, meaning that a person must inherit two copies of the O allele to express the O antigen. Because both the A and B alleles are codominant, neither is considered dominant over the other. Therefore, males do not carry the A allele as a dominant gene. Instead, they can inherit either the A or B allele from either parent, or they can inherit two copies of the O allele, which would result in the O blood type.

Is Gene a male or a female name?
Gene is a male name
Can a a b positive male and o positive female produce a o positive baby?
No as neither carry the B gene.
What gene is a male gene called?
Male genetics are found in the Y chromosome.
What causes a chicken to be a male or female?
The sex of a chicken is determined by genes when the egg is fertilized. It should be a 50/50 chance of male or female. And in the case of chickens it is the females that have the xy gene that determine sex and males that carry the xx gene, this is opposite of mammals where males with their xy gene determine the sex of the offspring.

Is the black male gene dominant over e white male gene?
Yes,
Could males be a carrier of a specific gene and not show traits?
Yes. It is possible for a male to carry a gene and not show it. However, it would have to be a recessive gene, therefore the trait would not show physically. Though, if it is a sex-linked gene, they would either show the trait or not. They cannot be carriers and not show it.
