MS-LS3-2 | Reproduction · NYS standard · Grade 8 test questions
Develop and use a model to describe how asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
Clarification statement: Emphasis is on using models such as diagrams and simulations to describe the cause and effect relationship of gene transmission from parent(s) to offspring.

NGSS Dimensions
Performance expectation MS-LS3-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop and use a model to describe phenomena.
- LS3.A: Inheritance of Traits
- Variations of inherited traits between parent and offspring arise from genetic differences that result from the subset of chromosomes (and therefore genes) inherited.
- LS3.B: Variation of Traits
- In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
- Cause and Effect
- Cause and effect relationships may be used to predict phenomena in natural systems.
