The answer is binomial nomenclature , also called binary nomenclature
If we name the gene for freckles with F, then the genotypes for having freckles are Ff (heterozygous), FF (dominant homozygous) and for no freckles ff (recessive homozygous).
If we name the gene for nose shape with N, than the genotypes for broad noses are NN (dominant homozygous) and Nn (heterozygous) and for narrow noses nn (recessive homozygous). A cross between two heterozygous:
P: FfNn x FfNn
F1:
9/16 are with freckles and broad noses
3/16 are with freckles and narrow noses
3/16 are with no freckles and broad noses
1/16 are with no freckles and narrow noses.
Answer:
Determine whether the trait has a dominant or recessive pattern of inheritance
Explanation:
This kind of information can be used to predict inheritance patterns in families. Depending on the genotypes, the dominant and recessive alleles and the different crosses, it can be deduced who are carriers of the disease and who express it. Similarly, by letting us know which chromosome (X or Y) is linked to the disease, we can know if the disease will be transmitted to the next generation depending on the genotypes of the parents.
A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
