recessive
What genes does a homozygous short pea plant always have?
Recessive genes
How can one trair disappear in one generation and then reappear in a later generation?
A trait can disappear in one generation due to a recessive gene being masked by dominant genes. When two carriers of the recessive gene have children, there is a 25% chance the trait will reappear in the next generation as the recessive gene is expressed. This is known as genetic recombination through Mendelian inheritance.
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.
Traits seem to disappear when two different genes for the same trait are present?
This phenomenon is known as dominance, where one gene masks the expression of another gene for the same trait. When an organism carries two different genes for a trait, one gene is dominant and determines the observable trait, while the other gene, known as recessive, is not expressed in the presence of the dominant gene.

According to Mendel what kind of genes disappear in F1 pea plants?
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both dominant and recessive alleles. The recessive phenotype disappears in the F1 generation because all members of that generation carry a dominant allele. In the F2 generation, the recessive phenotype will reappear.

Can recessive genes become dominant?
Recessive genes do not become dominant. Dominant genes mask the expression of recessive genes in the presence of both alleles. However, if a recessive gene is selected for over time through breeding, it can become more prevalent in a population.
When traits seem to disappear when two different genes for the same trait are present?
NO, the traits do not disappear they are simply "masked". According to Mendelian theory there are DOMINANT (A) and RECESSIVE (a) traits. When Aa is present the recessive trait is masked therefore it does not show up. These are called alleles.

Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
