Question

question 1 (1 point) listen imagine we had identified a gene involved in determining nose size. one version of this gene codes for a large nose and another version codes for a small nose. if a child inherits both versions of the gene, and their phenotype is that of having a small nose, what of the following is true? the small nose version of the gene is recessive the large nose version of the gene is dominant the small nose version of the gene is dominant both b and c

Explanation:

In genetics, a dominant allele is expressed in the phenotype even when a recessive allele is present. Since the child has a small - nose phenotype with both versions of the gene (large - nose and small - nose alleles), the small - nose version is dominant as it is the one being expressed.

Answer:

C. The small nose version of the gene is dominant
