Q: What human traits are controlled by more than one gene? Read this paragraph and choose the correct option from the provided answers: Many human traits are controlled by more than one gene. These traits are called polygenic traits (or characteristics). The alleles of each gene have a minor additive effect on the phenotype. There are many possible combinations of alleles, especially if each gene has multiple alleles. Therefore, a whole continuum of phenotypes is possible. Choices: - mutant traits - autolysis traits - maladaptive traits - polygenic traits A:
polygenic traits

Read this paragraph and choose the correct option from the provided answers: The age-sex structure of a population is the number of individuals of each sex and age in the population. Age-sex structure influences population growth. It is represented by a population pyramid. The number of survivors at each age is plotted on a survivorship curve. Choices: - habitat chart - density graph - biome model - population pyramid A:
population pyramid
