Answer:
Sedimentary rocks
Explanation: Where are fossils found? Fossils are found almost exclusively in sedimentary rocks—rocks that form when sand, silt, mud, and organic material settle out of water or air to form layers that are then compacted into rock. So the answer will be <em>Sedimentary</em> rocks.
When heterozygous advantage exists, the fitness of the heterozygous genotype has higher fitness than either homozygote.
<h3>What are genotypes and phenotypes ?</h3>
A person's genotype is made up of all the alleles they have for a certain gene. The sum of a person's attributes or observable characteristics is their phenotype. The phenotype of an organism is only impacted by its genotype, which is directly inherited from its parents.
<h3>Types of genotype :</h3>
There are three different genotype types: homozygous dominant (PP), homozygous recessive (PP), and heterozygous (Pp). The traits are the same in homozygous dominant and heterozygous genotypes.
<h3>
Heterozygous</h3>
The existence of two unique alleles at a specific gene locus. One normal allele, one mutant allele, or two separate mutant alleles may be present in a heterozygous genotype.
<h3>Homozygous </h3>
Contrary to a heterozygous genotype, a homozygous genotype exists. You inherited two copies of the same allele if you have a gene called homozygosity. In other words, both of your biological parents contributed the same variations.
