Science Benchmark

Information passed from parent to offspring is coded in DNA (deoxyribonucleic acid) molecules. The fundamental DNA structure is the same for all living things; the sequence of DNA differs between each organism and each species. Changes in the DNA sequence may alter genetic expression. The genetic information in DNA provides the instructions for assembling protein molecules in cells. The code used is virtually the same for all organisms. There are predictable patterns of inheritance. Sexual reproduction increases the genetic variation of a species. Asexual reproduction provides offspring that have the same genetic code as the parent.

Learning goals that need to be completed for every objective:

Rubrics for the objectives only ones listed here will be the ones to get you started and the ones I won't make you do on your own:

Objective 1: Compare sexual and asexual reproduction.

a. Explain the significance of meiosis and fertilization in genetic variation.

b. Compare the advantages/disadvantages of sexual and asexual reproduction to survival of species.

c. Formulate, defend, and support a perspective of a bioethical issue related to intentional or unintentional chromosomal mutations.

Objective 2: Predict and interpret patterns of inheritance in sexually reproducing organisms.

a. Explain Mendel’s laws of segregation and independent assortment and their role in genetic inheritance.

b. Demonstrate possible results of recombination in sexually reproducing organisms using one or two pairs of contrasting traits in the following crosses: dominance/recessive, incomplete dominance, codominance, and sex-linked traits.

c. Relate Mendelian principles to modern-day practice of plant and animal breeding.

d. Analyze bioethical issues and consider the role of science in determining public policy.
