There is only 1 unique phenotype observed in the offspring. As all offspring produced would have the genotype of Aa. In which the characteristic for the dominant allele will be seen in all offspring. As all offspring are Aa. There is only 1 unique phenotype. Here based on the characteristic or phenotype expression of the dominant allele.
The extinction of owls would increase the grasshopper population because the owls would not be eating any grasshoppers allowing the grasshoppers to reproduce and stay alive longer.
Answer:
The statement that best explains the mechanisms of inheritance of gene "The allele for blue is an X-linked dominant allele because there are no blue male offspring in cross 2."
Explanation:
The mechanism for inheritance of gene is the condition, in which the mutation when happens in one allele and cause the effect in the relevant phenotype. Similar inheritance will also be seen when the mutated allele will produce new type of the protein which will have deletorious effect on the normal function of the cell. In case of the single gene, autosomal dominant, autosomal recessive, X-linked dominant, X- linked recessive and mitochondrial are modes of inheritance.
