Examples of allele types are HH. That is option 2.
<h3>Gene Allele </h3>
An allele in genetic studies is an alternative gene form that is located at a particular point of the chromosome. It is usually represented with capital and small letter of the same alphabet.
There are two types of a allele which include:
Dominant allele: This is when the variation seen in a gene produces a noticeable phenotype. This is seen in the gene combination of HH.
Recessive allele: This type of allele does not produce any visible noticeable phenotype. This is seen in hh.
Animals derive energy by eating plants or animals and using cellular respiration to make ATP. Plants capture energy from the sun via photosynthesis and make sugar and oxygen. They can then use the sugar to perform cellular respiration to derive energy.
