Natural selection gizmo - Study guides, Class notes & Summaries

Exam (elaborations) GIZMOS Student Exploration Evolution Mutation And Selection Vocabulary: adaptation, allele, chromosome, evolution, fitness, gene, genotype, mutation, natural selection, phenotype, trait Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Imagine a white lizard and a brown lizard sitting on a brown rock. A hawk is circling overhead hunting for its next meal. Which lizard do you think the hawk would most likely try to catch? Explain your choice. The hawk...

Student Exploration: Hardy-Weinberg Equilibrium Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary : allele, genotype, Hardy-Weinberg equation, Hardy-Weinberg principle, heterozygous, homozygous, incompletely dominant, Punnett square Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A bird’s feather color is controlled by two alleles , D (dark feathers) and d (lighter feathers). Suppose two...

Student Exploration:Natural Selection Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary : biological evolution, camouflage, Industrial Revolution, lichen, morph, natural selection, peppered moth Prior Knowledge Questions (Do these BEFORE using the Gizmo .) The peppered moth ( Biston betularia ) is a common moth found in Europe, Asia, and North America. It is commonly found in two forms, or morphs : a dar...

1. What is fitness? The ability to survive and reproduce 2. What is an allele? A form of a gene or a gene variant. 3. How might a population’s gene pool help increase its fitness in an environment? A certain gene may be very good for its survival which will cause that organism to reproduce and have a better chance at survival. Gizmo Warm-up If natural selection does not favor one trait over another, the frequencies of various alleles in a population will tend to be stable over...

Student Exploration: Natural Selection Vocabulary: biological evolution, camouflage, Industrial Revolution, lichen, morph, natural selection, peppered moth Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The peppered moth (Biston betularia) is a common moth found in Europe, Asia, and North America. It is commonly found in two forms, or morphs: a dark morph and a light, speckled morph. Birds are a frequent predator of the peppered moth. 1. Which morph do you think would be e...
