The chance of this couple having a blond-haired child is 0%. Since black hair is dominant, both the parents must be heterozygous for hair color (Bb for black hair and bb for blond hair) for the man to be blond. If both parents are heterozygous, they would have a 25% chance of having a blond-haired child. However, if the woman has black hair, she must be homozygous dominant (BB) and the child would inherit at least one dominant allele for black hair.

How many does it reproduce?
Generally, an organism reproduces to produce offspring that can inherit its traits and continue its lineage. The number of offspring produced can vary significantly between different species and reproductive strategies. Some organisms produce many offspring with low chances of survival, while others produce fewer offspring with higher chances of survival.
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%.
How do you prove gene dominance?
Gene dominance is usually determined through breeding experiments. If one allele masks the expression of another allele in the heterozygous state, the masked allele is considered recessive while the masking allele is dominant. By observing the phenotypic ratios of offspring in controlled crosses, dominance relationships can be inferred.
A man and a woman are both heterozygous Freckles are dominant over no freckles What are the chances their children will have freckles?
There is a 75% chance that their children will have freckles and a 25% chance that their children will not have freckles. This is because both parents are carriers of the freckles allele and can pass it on to their offspring.
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 the child will inherit the Huntington disease allele from the mother and develop the condition. The inheritance of Huntington disease follows an autosomal dominant pattern, meaning the child has a 50% chance of inheriting the allele.
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.

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%.
Is shortness a recessive trait or a dominant trait?
Shortness can be either a recessive or dominant trait, depending on the specific genetic makeup of the individual. In general, if shortness is caused by a single gene, it is more likely to be a dominant trait. However, if shortness is influenced by multiple genes, it may be a recessive trait.
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.
Both a man and a woman are heterozygous for freckles Freckles F are dominant over no freckles f What is the chances that their child will have freckles?
PHENOTYPE: 75% with freckles 25% without freckles GENOTYPE: 1FF:2Ff:1ff

Why has a brush-tailed possum left my garden?
It is very rare for a possum to leave its territory permanently if it is not driven out by a dominant possum. Chances are high that, while out seeking a mate or foraging for food, it has been run over by a car or attacked by a dog.
