No Bell Question

We will discuss the answers to the Bell Questions and review the Hardy Weinberg Principle.

Students will then work on an Evidence of Evolution assignment.

If there is any time remaining, students will begin the homework assignment

1. Complete the Unit 7 Topic 9 Lecture Notes & begin working on the Phylogeny assignment, included in the packet. Due Tuesday 3/18

   1. • The video is in Google Classroom

      • We ware running labs for the next 3 classes. Unit 7 work will be given but we will not start addressing the concepts until after the labs.

Unit 7 Objectives and Understandings

If 108 out of 300 individuals in a population express the recessive phenotype, what percent of the population are heterozygotes?

A population of birds may have red feathers (the dominant phenotype) or orange feathers (the recessive phenotype). Red feathered birds have the genotype RR or Rr. Orange feathered birds have the genotype it. The frequency of the RR genotype is .46.

1. • What is the frequency of heterozygous birds?

   • What is the frequency of the R allele?

   • What is the frequency of the r allele?

A population of mice contains 20 animals with white tails and 30 animals with grey tails. Grey tails are the dominant trait.

1. • What is the frequency of the white allele?

   • What is the frequency of the grey allele?

   • What is the frequency of heterozygotes?

   • What is the frequency of mice homozygous for the grey allele?

We will discuss the answers to the Bell Questions and review the Hardy Weinberg Principle.

Students will then work on an Evidence of Evolution assignment.

Unit 7 Objectives and Understandings

Sixteen percent of a population is unable to taste PTC. These non-tasters are recessive for the tasting gene. Solve the following:

1. • What percentage of individuals in the population are tasters?

   • What is the frequency of the dominant allele in the population and the frequency of the recessive allele in the population?

   • What percentage of the population are heterozygous for the trait?

We will briefly discuss the two biotech labs we did, why we are not doing the third today and when we will conduct it.

We will then discuss Unit 7 and focus on the Hardy Weinberg formula.

1. 1. • We will watch the Bozeman video below on Hardy Weinberg and work through the problems at the end of the video

      • Students will then login to Gizmos and we, as a class, will work through the Hardy-Weinberg Gizmo

      • Students will then begin a Hardy-Winberg and Chi Square assignment.

1. Complete the Hardy-Winberg and Chi Square assignment.

2. Complete the Unit 7 Topics 6, 7 and 8 Lecture Notes. Due Wednesday 3/12

   1. • The videos are in Google Classroom

      • We ware running labs for the next 3 classes. Unit 7 work will be given but we will not start addressing the concepts until after the labs.
