Is it possible that a recessive trait in a survey such as this one may have a greater total number than its dominant counterpart explain how that might happen in a investigation like this?

Is it possible that a recessive trait in a survey such as this one may have a greater total number than its dominant counterpart explain how that might happen in a investigation like this?

No, not really. It is possible that a recessive trait in a survey such as this one may have a greater total number than its dominant counterpart. Because all of the offspring can inherit the same recessive trait.

What might cause a recessive trait to be more common?

Their genes may not necessarily reflect the original population’s genes. If they have a lot of homozygous recessive And heterozygous, the new population will have a high count of a recessive gene. Secondly, natural selection can sometimes have a recessive advantage.

Are recessive traits more common than dominant?

It is possible for recessive traits to be the most common (think blue eyes in Sweden) or dominant traits to be rare (think dimples everywhere). What makes a trait recessive has to do with the particular DNA difference that leads to that trait.

What does it mean for a trait to be dominant vs recessive?

Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present.

What is an example of a dominant trait?

Examples of Dominant Traits Curly hair is dominant over straight hair. Baldness is a dominant trait. Having a widow’s peak (a V-shaped hairline) is dominant over having a straight hairline. Freckles, cleft chin and dimples are all examples of a dominant trait.

What is an example of a recessive trait?

Examples of Recessive Traits For example, having a straight hairline is recessive, while having a widow’s peak (a V-shaped hairline near the forehead) is dominant. Cleft chin, dimples, and freckles are similar examples; individuals with recessive alleles for a cleft chin, dimples, or freckles do not have these traits.

How do you know if a trait is recessive?

If both parents do not have the trait and the child does, it is recessive. If one parent has the trait and the child does or does not, it is dominant.

What do you mean by recessive trait?

Description. A recessive trait is the weak, unexpressed trait of a dichotomous pair of alleles (dominant-recessive) that has no effect in the phenotype of heterozygous individuals.

Are blue eyes a recessive trait?

Eye color is not an example of a simple genetic trait, and blue eyes are not determined by a recessive allele at one gene. Instead, eye color is determined by variation at several different genes and the interactions between them, and this makes it possible for two blue-eyed parents to have brown-eyed children.

Are blue eyes from inbreeding?

Does inbreeding really lead to deformities and diseases could inbreeding actually be a good thing? For example, the gene for brown eyes is dominant and so having just one of these in a pair will result in your eyes being brown. However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes.

Are blue eyes the rarest?

Your eye color is largely determined by genetics. Green eyes are the rarest color. Brown eyes are the most common. People can also have blue eyes, (Learn More) gray eyes, (Learn More) or hazel eyes.

Can two people with blue eyes have a brown eyed baby?

Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child.

Can a baby have blue eyes if the parents don t?

The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby.

Which parent determines the eye color of baby?

What determines a baby’s eye color? In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby’s eye color is determined by the parents’ eye color and whether the parents’ genes are dominant genes or recessive genes.

Does breast size come from Mom or Dad?

Breast size is inherited from approximately 8 genes. These genes come from both your mother and father.
