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.
A man with freckles and a women without freckles with 3 kids with freckles and 1 without what is the genotypes of the parents and children?
The man must have a dominant gene for freckling and a recessive gene for no freckling. The woman has both recessive genes for no freckling. Therefore, there should be a 50% chance of getting the freckling gene and freckle in this family. If they had more children, chances are 50/50 that the baby will freckle.
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%.
What are the chances of having kids that can roll their tongue if a heterozygous tongue roller has kids with someone who cannot roll?
25%
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.
Why do children have characteristics of both their mother and father?
Children have similar characteristic's to their parents because when they are conceived, both of the parents genes unify to create a new set of characteristic'd depending on dominant and recessive traits. For example, Jane and Henry find out they are having a baby. Jane has homozygous blue eyes whilst Henry has heterozygous brown eyes. The chances are that their baby will either have 50% homozygous blue eyes or 50% heterozygous brown eyes.
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.
Can a short pea plant ever be produce from crossing two tall pea plants?
No, the short pea trait is recessive and the tall pea plant trait is dominant. This means that if the plant is a hybrid, it has to be a tall pea plant. The dominant traits "mask" the recessive traits. The plant take one trait from their mom and one from their dad. If either the mom or the dad was not a tall, not hybrid pea plant then their kids would have to be tall be cause they would have one dominant, tall trait
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.
What is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes?
Attached earlobes are a recessive trait. When one parent has attached earlobes and the other is heterozygous for free earlobes, the chances of any particular offspring having attached earlobes is fifty percent.
What are the chances of getting a square shape when 2 heterozygous square shapes are crossed?
75% 3/4 chance of it being square. 25% 1/4 change of it being round.
