Summary Introduction

To determine:

If it is possible to study the norm of reaction on a population of wild squirrels.

Introduction:

Phenotype is defined as the observable characteristics of an individual. The phenotype is affected by both genetic composition as well as environmental factors. The variation in the phenotype of an individual under different environmental conditions is defined as the ‘norm of the reaction’.

atural Selection - DA # 3 Flgure A shows the color of deer mice (Peromyscus maniculatus) In the Nebraska Sand Hills (white area) and the rest of the State (grey area). Mice are shown on the habitat they are not nomally found on. The color of the Sand Hills Is shown below the light-colored mouse (normal habltat), while the color of the ground in the rest of the State is shown below the dark-colored mouse. Figure B shows the phenotyplc difference in the hair shaft of the wild-type and the light-colored (wideband) mice. Figure C shows the expressilon levels (MRNA) of the Agouti alleles responsīble for the phenotype seen in figure B. a+= wild-type Agouti alele, a-= a deletion of the Agouti allele, awb = wideband Agouti allele mutation, and the black rectangles undermeath each bar is the relative difference in the hair shaft band phenotype. Wder band means lighter hair color in the deer mice. b. The Sand Hills were created by volcanic activity 15,000-8,000 years ago. How were the deer mice…
EXERCISE 6 HARDY-WEINBERG EQUILIBRIUM Work in a small group or alone to complete this exercise. In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f'is the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (F) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f ) and 70% (0.7) are dominant (F). 1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show your work. 2. You have collected data on the observed genotype frequencies of the next generation. They are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?
