Is it possible to have a phenotype different from either parent?

In some instances, offspring can demonstrate a phenotype that is outside the range defined by both parents. In particular, the phenomenon known as overdominance occurs when a heterozygote has a more extreme phenotype than that of either of its parents.

Is it possible for two parents who have the same phenotype look the same to have different genotypes?

It is also tall. The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).

Is phenotype inherited from parents?

A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

How a child can have a different phenotypic characteristic that neither parent has?

How might it be possible for you to show a trait when neither of your parents show the same trait? It can be carried to you when the chromosomes combine even if the parents don’t possess the same trait. It can skip and be dominant for you, so you would be able to see it in your genetic make up.

Do all humans have the same phenotype?

Everyone has a unique phenotype — even identical twins. For most people, your genotype is unique, and even if you’re an identical twin you may be subject to different environmental influences and experiences than your twin; as a result, your phenotype will be different.

How can two people have the same phenotype but different genotypes?

Mandira P. Same phenotype but different genotype is possible due to presence of dominant allele. … A person can have a dominant allele on both the homologous chromosomes (i.e. in double dose) while another person may have single dominant allele and a corresponding recessive allele.

How many different phenotypes are possible in the offspring?

Figure 13: The possible genotypes for each of the four phenotypes. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.

Can you change your phenotype?

A phenotype is the composite of an organism’s observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, phenology, behavior, and products of behavior. If you can change the environment (including your internal environment) then you can change your phenotype.

What is the possible phenotype?

The phenotype is the physical manifestation of an organism’s allellic combination (genotype). For the pea plants, if the red allele is dominant and the white allele is recessive, only two phenotypes are possible. … The phenotype can be either red or white flower color, depending on the genotype.

Is it possible for genotype to change?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

Is it possible to show a phenotype that your parents do not have?

In some instances, offspring can demonstrate a phenotype that is outside the range defined by both parents. In particular, the phenomenon known as overdominance occurs when a heterozygote has a more extreme phenotype than that of either of its parents.

How might it be possible to show a trait when both parents do not show it?

4) A person can only show a recessive trait if both of his parents carried at least one copy each of the recessive allele. The parents do not need to show the trait, as one copy is not enough to reveal it, but they must both carry it.

Is it possible for two parents to express a trait and their offspring does not express that trait?

Unaffected parents can produce affected offspring if both parents are carriers (heterozygous) for the trait being tracked in the pedigree. Recessive traits are typically not expressed in every generation. Lastly, males and females are equally likely to express a recessively inherited trait.

IT IS SURPRISING:  Best answer: Do similar species have similar numbers of chromosomes?

Why do humans have different phenotypes?

While human phenotypes may seem diverse, individuals actually differ by only 1 in every 1,000 base pairs and is primarily the result of inherited genetic differences. … The trait is still the result of variance in genetic sequence between individuals as a result of inheritance from their parents.

Can siblings have different genotypes?

X and Y chromosome differences mean that brothers and sisters can never have identical genotypes. However, brothers have the same DNA on their Y chromosomes.

Is it possible for twins to have different genotype?

About one-third of twins are monozygotic twins. … The result is dizygotic or fraternal twins. These two individuals share the same amount of genetic material as would any two children from the same mother and father. In other words, they possess a different genotype and phenotype.
