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.
If a boy is born with attached earlobes, he must have inherited two recessive alleles (ee), one from each parent. This means that both parents must either be carriers of the recessive allele (Ee) or express the attached earlobe phenotype themselves (ee). Therefore, at least one of the parents must have the recessive allele for attached earlobes.
Person A must carry at least one dominant allele for unattached earlobes, as they are not shaded gray and therefore do not express the recessive trait of attached earlobes. If A had two recessive alleles, they would exhibit the attached earlobe trait. Additionally, A could be homozygous dominant or heterozygous for the trait, meaning they might have a parent or sibling with attached earlobes as a result of inheriting the recessive allele.
At some time during their lives, all cells must contain DNA.
True
True. Ribosomes stud the surface of rough endoplasmic reticulum.
He has a homozygous genotype
If a boy is born with attached earlobes, it indicates that he has inherited a specific genetic trait. Attached earlobes are typically considered a recessive trait, meaning that both parents must carry the gene for it to be expressed in their child. Therefore, at least one or both of the boy's parents likely have attached earlobes or carry the allele for the trait.
If a boy is born with attached earlobes, he must have inherited two recessive alleles (ee), one from each parent. This means that both parents must either be carriers of the recessive allele (Ee) or express the attached earlobe phenotype themselves (ee). Therefore, at least one of the parents must have the recessive allele for attached 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.
Person A must carry at least one dominant allele for unattached earlobes, as they are not shaded gray and therefore do not express the recessive trait of attached earlobes. If A had two recessive alleles, they would exhibit the attached earlobe trait. Additionally, A could be homozygous dominant or heterozygous for the trait, meaning they might have a parent or sibling with attached earlobes as a result of inheriting the recessive allele.
He has at least one E allele is correct. I take the quiz
He has no E alleles.
He has at least ONE E allele
if they are not a true seal the they do have ear
true
yes of course
Yes
