if a trait is recessive, it can only be expressed if its other trait is recessive as well. If the other trait in the genotype is dominant, it will block the recessive factor. But if both are recessive, they will be able to be seen in the offspring.

What does it mean to have a dominant trait?

In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.


How do you know from a pedigree diagram if a trait is dominant or resessive?

If a trait is dominant, it will appear in every generation where at least one parent has the trait. If a trait is recessive, it can skip generations and may appear in offspring of parents without the trait. Dominant traits are usually expressed in every generation, while recessive traits can "hide" and reappear later.


A trait that appears or is expressed in the f1 generation is what?

A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.


Two individuals heterozygous for a single trait have children what is the expected phenotypic ratio of the possible offspring?

Let T=trait (dominant) Let t= trait (recessive) Father has Tt and mother also has Tt The possible combinations for offspring are: TT Tt Tt and tt Therefore There is a 3/4 change of the offspring having the dominant trait and a 1/4 Chance of the offspring having the recessive trait It should also be noted that there is a 1/4 chance of the offspring carrying two dominant genes meaning that any of their children will also share the dominant trait


The trait observed in the first generation when parents that have different traits are bred?

The trait observed in the first generation when parents with different traits are bred is known as the dominant trait. This trait is expressed in the offspring because it masks the expression of the recessive trait.

What is the kind of trait that seemed to appear in the offspring produced in Mendel's first experiment?

A dominant trait appeared in the offspring produced in Mendel's first experiment.


What is a dominat trait dictionary?

A dominant trait is part of genetics in which a trait will appear in an offspring if one parent contributes it. For example, if one parent contributes the dominant trait of dark hair and the other contributes the recessive trait of light hair, the offspring would have dark hair.


If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?

Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.


A parent that is homozygous for a dominant trait is crossed with a parent that is homozygous for the recessive trait What percentage of the offspring will display the dominant trait?

100% of the offspring will display the dominant trait because the homozygous dominant parent can only pass on the dominant allele. The offspring will inherit one dominant allele from the dominant parent and one recessive allele from the recessive parent, resulting in a heterozygous genotype expressing the dominant trait.


What does Gregor Mendel law of dominance state?

Mendel's law of dominance states that if you have a pair of genes then the one that shows up in the offspring is most likely the dominant gene because the dominant is passed along more often than the recessive.


Which type of genetic trait appears in every generation of offspring?

A dominant genetic trait appears in every generation of offspring because only one copy of the dominant allele is needed for the trait to be expressed.

Can a white offspring be a hybrid why?

If the white trait is dominant, then yes. If the white trait is recessive, then no.


How can offspring inherit a recessive trait?

An offspring can inherit a recessive trait if both of its parents are homozygous for the dominant allele.

Father with homozygous genes for dominant trait?

This means that the father has two copies of the dominant allele for a particular trait. As a result, all of his offspring will inherit at least one copy of the dominant allele from him. This implies that all his offspring will either express the dominant trait or be carriers of the dominant allele.


A trait that appears or is expressed in the f1 generation is what?

A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
