If two heterozygous parents mate, the phenotypes of the resulting offspring will be 75% dominant and 25% recessive
Answer:
cells and structure
Explanation:
the place where they live cannot be a basis of classification
Actually, it is false. P-waves arrive first and then S-waves arrive.
I believe the answer is D, Cells get energy by taking in nutrients from food. Correct me if I'm wrong.
Complete question:
Question: When crossing two individuals, the offspring display only one of the two traits found in parents. Which principle of Mendelian genetics is supported by this observation?
a) segregation
b) independent assortment
c) dominance and recessiveness
d) allele frequency
Answer:
c) dominance and recessiveness
Explanation:
According to Mendel's principle of dominance and recessiveness, the alleles of one gene may be dominant or recessive in nature. When present together, only the dominant allele is able to express itself. Therefore, a hybrid individual for a gene would express only the dominant phenotype. In the given cross, the progeny express only one of the two traits found in the parents. This means that the progeny is heterozygous for the trait and is expressing the dominant trait. The recessive trait is not expressed due to the presence of the allele for the dominant trait.
