The probability of a homozygous recessive offspring resulting from a cross between two homozygous dominant individual is?
It depends on the parents. The parent could have two dominant genes which would give a 0% chance of the offspring being recessive. The only way that the offspring could have a recessive characteristic is if the both parents have one dominant and one recessive gene, a 25% chance. The chance that both parents would pass on the recessive gene (if they have one dominant and recessive gene) is also 25%, because there is a 50% chance for each parent.
Is a disorder know as a dominant or recessive?
Dominant disorders can be passed onto the offspring if the dominant gene is present in the offspring.
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
Can a person with a genetic disorder that has been corrected with gene transfer pass it on to its offspring?
No because the regular gene is dominant to the resecccsice one suckas

Dominant disorders can be passed onto the offspring if the dominant gene is present in the offspring.
What is the Mode of inheritance hemophilia?
Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.
Why is a son who receives the allele for combinations from his mother always colorblind?
Since the mother would be considered a carrier, the gene will be produced in the offspring. the son will receive that gene and will be colorblind.
When is gene pool is considered stable?
when the traits are dominant and are passed down to the offspring.
A living thing with a dominant and recessive gene for a trait?
A living thing with a dominant and a recessive gene for a trait is heterozygous. This individual will display the dominant phenotype for that trait but may have offspring that display the recessive trait.
If both a mother and a father carry a dominant gene for dark eyes and a recessive gene for light eyes (Bb) what is the likelihood that their offspring will have dark eyes?
75%. If both parents are heterozygous, then using a punnet square, one can see that the dominant gene will show up in 3 out of 4 offspring.
Can 2 people with Huntington's Disease produce an offspring who does not have Huntington's disease?
Unfortunately, no. Huntington's is carried on a dominant gene. One parent HD, one non-HD, you have a 50-50 chance of not inheriting that gene. But two parents that are HD, you will inherit the gene from one parent or the other.
Are blue eyes a dominant trait?
no they are a recessive gene. You would receive a blue gene from each parent
What are the chances of a person with marfan syndrome passing it to their offspring?
Have a 50% chance of passing it on to there offspring. This is called an autosomal dominant gene. What that means is, considering each human has TWO sets of chromosomes (1 from mom, 1 from dad), it takes only ONE copy of the mutated gene being passed on for the child to inherit the syndrome. Because for the conception of each child there is a chance of passing one or the other gene on, there is a 1 in 2 or 50% chance of giving the child Marfan Syndrome.
There is a 50 percent chance the genotype of the offspring will contain a dominant geneCould this count as a correct way to explain the outcome of a punnet square?
No. The punnet square should yield 75% dominant. If the sides of the square are A and a versus A and a, capital A meaning the dominant gene, which expresses over the recessive gene "a" whenever it is present, then the possible outcomes in the square are: AA, Aa. aA, and aa. Three out of four, or 75%, are dominant.
How come there are no carriers in genetic diseases caused by dominant alleles?
If carried on a dominant allele, you either inherit it- and have the disease- or you don't- and do not have the disease, nor the gene that causes it. If you don't have the gene, you can not pass it to your offspring.
