Interpret the following scenario to distinguish between recessive and dominant forms of inheritance. Two unaffected parents that are heterozygous for a genetic disease have a child with the genetic disease. This form of inheritance follows a recessive form of inheritance.
<h3>What is genetic disease?</h3>
A person needs two recessive alleles to display a recessive trait, yet only one dominant allele can express a dominant trait.
Dominant alleles serve as a cover for recessive alleles.
When a gene is inherited from only one parent, and a normal gene is inherited from the other parent, the offspring will not have the condition.
When a gene is inherited from either parent, the offspring will inherit that genetic condition or characteristic.
Long DNA strands are arranged into genes on chromosomes that code for particular characteristics.
These particular features can be passed down through the genes as well.
When present, dominant behavior is always apparent.
Only when dominant genes are absent does recessive gene expression occur.
Its natural selection. Due to genetic variations, some animals have traits more desirable then others. This animals will survive and reproduce better, over time creating a whole new species.
Respiration is when animals breathe in oxygen and use it to produce energy, releasing carbon dioxide and water as by-products. In simpler terms, it is the act of breathing.
