Which a students mother Is heterozygous for attached earlobes a recessive trait. The student father Is Also a heterozygous for that trait. What is the percent likelihood that his earlobes are atta?
If both parents are heterozygous for attached earlobes (genotype Ee, where E is the dominant allele for free earlobes and e is the recessive allele for attached earlobes), the possible genotypes for their child can be determined using a Punnett square. The possible combinations are EE, Ee, Ee, and ee. This means there is a 25% chance (1 out of 4) that the student will inherit the genotype ee, resulting in attached earlobes. Thus, there is a 25% likelihood that the student has attached earlobes.
What must be true if a boy is born with attached earlobes?
If a boy is born with attached earlobes, it means that he inherited the trait for attached earlobes from at least one of his parents. This trait is determined by genetics and is a dominant trait.
What happens when a person receives on alle for attached earlobes and one for unattached earlobes?
there one alle for free ear-lobes and another allele for attached if your gene for ear-lobes is made up of two alleles for free ear-lobes your ear-lobes are NOT attached and if you have two attache-ear-lobes alleles your ear-lobes are attached
What are the phenotype attach earlobes?
Earlobes that are attached to the face rather than ones that hang freely (de-attached)
If you know that the allele for attached earlobes is recessive and a friend of yours has attached earlobes what do you know about your friends the mothers and the fathers genotype?
If your friend has attached earlobes (recessive trait), then your friend must have two copies of the recessive allele for attached earlobes (aa). This means that both of your friend's parents must be carriers of the recessive allele (Aa) in order to pass it on. Your friend's mother and father would both have one dominant allele (A) for free-hanging earlobes and one recessive allele (a) for attached earlobes.
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.
Earlobes can be either attached or detached. The allele for attached earlobes is recessive and the allele for detached earlobes is dominant. What must be true is a boy is born with attached earlobes?
He has a homozygous genotype
What percentage of people in United States have detached earlobes?
Studies show that roughly seventy percent of people in the world have detached earlobes, leaving thirty percent with attached earlobes. However, this is only a rough estimate based on data collected.
Why do more people have attached rather than unattached earlobes?
The presence of attached or unattached earlobes is determined by genetics. The trait for unattached earlobes is dominant, meaning that it is more common in the population. This is why more people tend to have attached earlobes.
Which a students mother Is heterozygous for attached earlobes a recessive trait. The student father Is Also a heterozygous for that trait. What is the percent likelihood that his earlobes are atta?
If both parents are heterozygous for attached earlobes (genotype Ee, where E is the dominant allele for free earlobes and e is the recessive allele for attached earlobes), the possible genotypes for their child can be determined using a Punnett square. The possible combinations are EE, Ee, Ee, and ee. This means there is a 25% chance (1 out of 4) that the student will inherit the genotype ee, resulting in attached earlobes. Thus, there is a 25% likelihood that the student has attached earlobes.
Does gender matter when determining the odds of someone having attached or unattached earlobes?
No knucklebrain
Both you and your sister or bother have attached earlobes yet your parents have unattached earlobes unattached earlobes are dominant over attached earlobes what are the genotypes of your parents?
If both you and your sibling have attached earlobes (aa genotype) and your parents have unattached earlobes, then your parents must both be carriers of the recessive allele for attached earlobes (Aa genotype).
Free earlobes in humans is a dominant trait if two parents with free earlobes have children with attached earlobes the genotype of the parents must be?
If two parents with free earlobes have a child with attached earlobes, both parents must have the genotype of heterozygous (Ee) for earlobe shape. Free earlobes (E) is dominant over attached earlobes (e), so the presence of attached earlobes in their child indicates that both parents are carriers of the recessive allele for attached earlobes.
What is the ratio of free earlobes to attached earlobes?
The ratio is approximately 4:1, with free earlobes being more common than attached earlobes in the general population.
How can you tell if you have attached or detached earlobes?
If they attach directly to the side of the head, they are attached earlobes. If they don't they are unattached.
What must be true if a boy is born with attached earlobes?
If a boy is born with attached earlobes, it means that he inherited the trait for attached earlobes from at least one of his parents. This trait is determined by genetics and is a dominant trait.
What is the probability that a father produces a gamete with the allele for attached earlobes if he has one allele for detached earlobes and one allele for attached earlobes?
