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?
50%
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 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
Is detached earlobes recessive or dominant?
Dominant. he has a homozygous genotype
What must be true if a boy is born with detached earlobes?
If a boy is born with detached earlobes, both of his parents must have detached earlobes as well, as this trait is inherited. Detached earlobes are a recessive trait, meaning that both parents must pass on the gene for detached earlobes in order for the child to have them.
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.
Have both parents got to have ear lobes to have a child with lobes?
No, (free) earlobes follow a simple genetic dominance relationship, where free earlobes are dominant over attached earlobes. Meaning that having one parent with free earlobes suffices for the child to also share that trait.
My left forearm has been swollen for over a year. It is about one and one half times as big as my right arm. What could that be?
My guess is a drainage problem, likely with the Lymphatic system. The only way to know for certain is to see a doctor.
What type of earlobe is dominante?
Free-hanging earlobes are considered the dominant trait, while attached earlobes are recessive. This means that if an individual has at least one parent with free-hanging earlobes, they are more likely to have free-hanging earlobes themselves. The genetic basis for this trait is linked to variations in specific genes.
What is the meaning of detached earlobes?
Detached earlobes refer to earlobes that hang freely and are not connected to the side of the head. This trait is a genetic variation, with earlobe shape being influenced by heredity. Detached earlobes are often considered a dominant trait, meaning they can be passed down from one generation to the next. In contrast, attached earlobes are connected directly to the head without a free-hanging section.
What is the phenotype of a man who has 2 parents with free hanging earlobes if one parent is homozygous and the other parent is heteroygous... what are his possible genotypes?
The man could have either free hanging or attached earlobes. His possible genotypes could be either homozygous for free hanging earlobes (LL) or heterozygous for free hanging and attached earlobes (Ll).
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.
