The purpose for which a pedigree chart might be prepared is to identify the pattern of inheritance of a particular trait.
This pedigree chart is created so as to see which traits this new offspring has inherited from its ancestors and which may possibly be transferred onto a new offspring later on in its life. It is formed in order to find patterns of inheritance and see what the most important traits that get inherited are.
Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.

The bones are: malleus (hammer-shaped) , incus (anvil-shaped) and stapes (stirrup-shaped).
They are together known as ear ossicles.
They transmit the vibrations from the eardrum or tympanum to the inner ear.
Explanation:
Groundwater is the freshwater present below the earth's surface. It originates from the rain, ice, melting snow.
Some anthropogenic sources of groundwater pollution are
Groundwater pollution has more problems than surface water pollution because groundwater is mostly hidden and it is very difficult to view, manage and monitor.
Groundwater holds its contamination and pollutants that cause pollution whereas surface water rinses their contamination and pollutants.
