How do you understand that attachment of ear lobes are inherited?
Whether or not an ear lobe is attached at its base or not depends on whether or not that person's parents had attached earlobes or not. If both parents have attached earlobes, then their children will also have attached earlobes. If both parents have detached earlobes, then their children will also have detached earlobes. But if one parent has detached earlobes, while the other has attached earlobes, their child's earlobes may be detached, attached, or only slightly attached. This is because each parent provides part of the DNA (deoxyribonucleic acid) molecules that exist at the center of almost every human cell. Since the cells of the body don't "know" anything, they just follow the "instructions" that DNA provides them by building themselves according to how the DNA molecule says they should be built. How this actually works is a complicated chemical process that would be better answered in a separate question, but you don't need to know how it works, only that the result is this - children get some instructions for how to build their body from their mother, and some from their father. If the instructions agree, then the cells that make up the ear will grow a definitely attached or detached earlobe. If the instructions in the child's DNA disagree, then you might get a mix, or the cells might end up paying attention only to one set of instructions or another.
Asked in Genetic Diseases
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?
Asked in Biology
Attached earlobes are recessive to free earlobes What genotypic ratio is expected when an individual with attached earlobes mates with an individual heterozygous for free earlobes?
Asked in Head, Ears, and Nose
What does it mean if you have two different earlobes?
Attached earlobes or unattached earlobes dominant?
Why do more people have attached rather than unattached earlobes?
Asked in Biology, Genetics, The Difference Between
Is attached earlobes or unattached earlobes dominant?
It was said earlier that, "Unattached earlobes are the dominant trait, twice as many people have unattached earlobes compared to attached." There is not actually any real proof that unattached earlobes are dominant. While more people may have unattached earlobes, attached earlobes are dominant. This was proved in a pedigree which covered three generations of extended families.
