Recessive genes can persist in a population because they can be carried in individuals without being expressed. These hidden recessive genes can be passed down through generations, only showing up if inherited from both parents. Additionally, genetic diversity can help maintain recessive genes in a population even if they are not expressed in every generation.
Recessive genes
An organism's unseen recessive genes are included in its genotype, which is the complete set of genetic information inherited from its parents. While these recessive alleles may not be expressed in the organism's phenotype (the observable traits), they can still be passed to offspring. If an organism carries two copies of a recessive allele, or one copy alongside a dominant allele that does not mask it, the trait can become visible in subsequent generations. Thus, recessive genes play a crucial role in inheritance and genetic variation.
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
Yes, dominant and recessive genes play a role in determining physical traits in offspring. Dominant genes are more likely to be expressed in the phenotype, while recessive genes are typically masked unless an individual inherits two copies of the recessive allele. This interplay between dominant and recessive genes contributes to the variety of physical characteristics seen in offspring.
Yes, recessive traits can skip generations because they can be carried in the genes of individuals without being expressed in their physical characteristics.
That will depend on what traits those genes control.

He studied dominant and recessive genes. He studied pea plants and the traits that they obtained from previous generations.
The dominant genes take over, and then the recessive genes hide away
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.

Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
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.
No genes disappear in the F1 generation. Each of the F1 plants was heterozygous, having both a 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.
