Adaptive Traits and Genetic Inheritance

Miss Jetta introduces a lesson on natural selection, focusing on adaptive traits and reproduction. The lesson includes a warm-up activity about bird beaks, a simulation to test reproduction claims, and an analysis of trait distribution over generations. The video also covers genetics, explaining how genes and proteins determine traits. The lesson concludes with reflection questions to reinforce learning.

What materials are suggested for the lesson on natural selection?

• A textbook and highlighter

• A pencil or pen and paper

• A calculator and notebook

• A ruler and eraser

What trait is considered adaptive for the birds in Sherman's story?

• Colorful feathers

• Long legs

• Sharp claws

• Strong and tough beaks

In the simulation, what was observed about the offspring of Australopes with non-adaptive traits?

• They had the same non-adaptive traits

• They always had adaptive traits

• They had a mix of adaptive and non-adaptive traits

• They had completely different traits

What is the role of genes in determining traits?

• Genes directly create traits

• Genes allow organisms to change their traits at will

• Genes are random and do not affect traits

• Genes provide instructions for making proteins, which determine traits

How do jellies acquire the gene for glowing?

• By exposure to certain chemicals

• By absorbing light from the environment

• Through a special diet

• By inheriting it from their parents

What are alleles?

• Different versions of a gene

• Chromosomes that contain DNA

• Proteins that determine traits

• Cells that carry genetic information

How many chromosomes do humans inherit from each biological parent?

• 23 in total

• 46 from each parent

• 23 from each parent

• 46 in total

What is the relationship between genes, proteins, and traits?

• Traits determine the structure of genes and proteins

• Genes create traits directly

• Proteins create genes, which create traits

• Genes provide instructions for proteins, which determine traits

How can an individual be born with an adaptive trait?

• By choosing the trait at birth

• Through environmental influence

• By inheriting genes for the trait from parents

• By random genetic mutation

What determines the traits of offspring in a population?

• The environment they are born into

• The traits of their parents

• The food they consume

• The climate they live in
