A man and a woman are both heterozygous Freckles are dominant over no freckles What are the chances their children will have freckles?
a 100% chance for freckles.
How do you prove gene dominance?
When two heterozygous organisms are mated, approximately 75% of these organisms should display the trait if it is dominant. 25% would display the recessive gene. If these numbers are very far off, chances are the gene you were testing was not a dominant trait.
Which is the dominant gene father has dark brown eyes mother has blue eyes?
Sure you don't mean heterozygous dominant? If you don't there would be no blue eyed offspring. Let's assume you meant heterozygous dominant.B = brownbl = blueBbl X Bbl1/4 of the offspring would have blue eyes, 25%.
A woman heterozygous for Huntington disease reproduces with a man without the condition. What are the chances the child will have the condition?
There is a 50% chance that Mary's mother passed along her gene for HD. Since this cannot be "canceled out" by her father's unaffected genes, Mary has a 50% chance of having and expressing that bad gene. If Mary's father was also heterozygous for HD, there would be a 75% chance that she would get at least one bad gene.To add the the answer above, Huntington's disease doesn't typically show itself until a person is between 35 to 50 years of age. The reason that the normal genes for the father don't "cancel out" any affected genes passed on my the mother is because this is a dominant genetic disorderthere are lots of diseases and they keep on being made. PS. stay safe and disease free.
Is brown or red hair the dominant gene?
Normally when the red and brown hair genes infuse with each other, the brown would come more dominant. For some notable reasons. Red hair (otherwise known as ginger hair) is a genetic mutation between blondes. Its inheritance chances are very low (usually 5-10%), while brown hair is somewhat an adaption between black hair and blonde hair. Thus with a higher chance.
A man and a woman are both heterozygous Freckles are dominant over no freckles What are the chances their children will have freckles?
a 100% chance for freckles.
What are the chances a child will be born with a hereditary disorder or disease?
Depends on the disease- dominant gene or recessive gene- and the genotypes of the parents.

Brown eyes are dominant Cross a homozygous brown with a recessive blue What color eyes will the offspring have?
all brown the chances of brown eyes both parents have to have blueeyes for blue eyes to become dominant but its still possible no matter what for blue or brown
What are the chances that a father and mother with genotypes AA will give birth to a child with genotype AS?
25% The four possibilities are aa as as ss
Mother has light green eyes father has hazel what color would their baby have?
This depends on their recessive and dominant genes, and therefore the chances they would have of having a child with a certain colour eyes.
What is jerry mandarin?
If you are asking what is Jerry Mandarin? Then it is not a name, not a fruit, not a dialect. Gerrymandering, means to run for office under the political party that is dominant so the person can have higher chances of winning.
What is an individual with genotype AAA described as?
An Aa genotype can result in the same phenotype as either an AA or AA genotype, if one of the alleles acts in a dominant fashion. If the A allele is dominant over the a allele, then the phenotype of a heterozygous (Aa) individual will be the same as the phenotype of a homozygous dominant (AA) individual.

Is shortness a recessive trait or a dominant trait?
Usually recessive, unless it runs in your family. Otherwise many people would be short. ADDED: Actually the above answer is wrong! Achondroplasia is a dominant genetic condition, This shows that names of biological/genetic conditions do not always mean what they would in normal usage. This is a case of recessive alleles driving themselves into the populations gene pool because the dominant gene is deleterious. Polydactal condition ( extra fingers/toes ) is also a dominant condition.
What color horse will you get if you breed a golden dun horse with a black horse?
It depends on what is the dominant trait. Its all to do with the dominant and recessive genes of the parents. Each parent will have two chromosomes for color and the foal will have one from each. Most likely you will get either a dun or black but the specific chances of that happening can only be found out if more research is done into the parents and grandparents' genes.
