Georgia S7L3

S7L3 is a Georgia science standard. These are the elements under it.

• S7L3.a

  Construct an explanation supported with scientific evidence of the role of genes and chromosomes in the process of inheriting a specific trait.

• S7L3.b

  Develop and use a model to describe how asexual reproduction can result in offspring with identical genetic information while sexual reproduction results in gen...

• S7L3.c

  Ask questions to gather and synthesize information about the ways humans influence the inheritance of desired traits in organisms through selective breeding.

01

What Students Need to Do

Students compare sexual and asexual reproduction and trace how genetic information passes from parent organisms to offspring. They use evidence to explain why offspring may resemble their parents yet differ from them.

02

What Mastery Looks Like

Students can identify the type of reproduction shown in an example and describe how many parents contribute genetic information. They can use a simple inheritance model to predict possible offspring traits and explain variation.

03

Common Misconceptions

Students may think all offspring are exact copies of their parents or that one parent controls each trait. They may also confuse inherited traits with traits gained through experience, such as scars or stronger muscles.

04

How to Assess It

Give students one example of bacterial division and one allele chart for two parents. Ask them to identify each reproductive pattern and explain the expected offspring similarities or differences.

1. 01

   Give students colored allele cards to model genetic transfer in sexual reproduction, then compare their varied offspring with copied cards in asexual reproduction.

2. 02

   Ask students to write why siblings from the same parents can look different while bacteria produced by division are usually very similar.

3. 03

   Play an inheritance matching game where students pair parent allele cards, build possible offspring combinations, and name the traits each combination produces.

4. 04

   Use dog breeding or crop cuttings to compare how people use sexual and asexual reproduction to preserve or combine desired traits.

• S5L2

  Obtain, evaluate, and communicate information showing that some characteristics of organisms are inherited and other characteristics are acquired.

• S7L5

  Obtain, evaluate, and communicate information from multiple sources to explain the theory of evolution of living organisms through inherited characteristics.

• S7L4

  Obtain, evaluate, and communicate information to examine the interdependence of organisms with one another and their environments.

• S2L1

  Obtain, evaluate, and communicate information about the life cycles of different living organisms.
