Is it possible to have attached earlobes if both of your parents have unattached earlobes?

Yes it is your possibility if the parents were both heterozygous(having different alleles) or hybrid with Aa and Aa, the genotypic ratio would be 1:2:1 so if you put it in a punnet square there is a 25% chance of AA, 50% chance of Aa and 25% chance of aa.

∙ 6y agoAttached earlobes are a recessive trait, so the child's parents would be heterozygous for the trait with a 25 percent probability of producing a child attached earlobes.

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?
the gene is not shown in their chara ter
If both of the parents have attached earlobes what is their genotype?
The phenotypes of attached and unattached earlobes do not fit neatly into the Mendelian theory of two alleles for one trait, and there is a continuum of earlobe phenotypes. That said, unattached earlobes are a dominant trait, so if the individual is homozygous for unattached earlobes, all of her offspring will have the unattached phenotype, even if some or all of them are heterozygous.
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?
the genotype would be for the mom Ee and for the dad it would be Ee.
What do the letters inside the punnent square stand for?
The letters on the outside are the genotypes of two parents. Inside are the possible genotypes of possible offspring of the two
Genetic recombination is possible because of?
new combinations of genes from two parents

A child is born with attached earlobes but both parents have hanging earlobes. What are the genotypes and phenottypes fot the parents?
lets use "A" Aa and Aa aa

the genotype would be for the mom Ee and for the dad it would be Ee.
Is ear shape genetic?
yes, for the most part. The DNA in your genes code for the size, shape and structure of all your physical features- but environmental factors, such as the positioning inside the uterus, can slightly alter the outcome. this is why identical Twins, who have the exact same DNA, end up with different fingerprints
What characteristics make humans unique?
The eye color, the hair color, the genetics that make it a boy or girl, the height in which the baby will grow(which is depended on the height of the parents), the skin color, the diseases that the child could have later in their life which is also depended on the diseases that the parents had or have, and etc...
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.
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 possible genotypes HH and Hh. 50% homozygous for hanging earlobes (HH), and 50% heterozygous for hanging earlobes (Hh).
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.
Predict what genotype the children will have if one parent is homozygous recessive for earlobes and homozygous dominant for hairline (eeWW) and the other parent is homozygous dominant for unattached earlobes and homozygous recessive for hairline (EEww )?
The only possible outcome is EeWw, which will express the dominant genes but carry the recessive ones. They get one chromosome from each parent, but since the parents all have matching chromsomes in this case then it doesn't matter which one they get. Since one parent has EE, E is the only one that can be passed on. Since the other has ee, they can only pass on e. Therefore, the child can only possible have Ee, as they get one from each parent.
Can you name about 12 traits you can inherit from your parents?
* receding hairline * gapped teeth * widow's peak (hairline that comes down on forehead, gives a heart shaped look) * attached or unattached earlobes * webbed toes * interlocking fingers * spock finger spread * cleft chin * rolled or unrolled tongue * pinkie bent towards other fingers or away from * mid-digital hair (having hair on one or more of your fingers on the middle joint)
Does a wasp resemble its parents?
it is possible that a wasp can resemble its parents because of genetics. if a child can resemble its parents, it will be possible that a wasp can resemble its parents. it might not be physical but possible it its genetic coding.
