Summary Introduction

Introduction: The plasma membrane is the outermost layer of a cell which gives definite shape and protection to the contents of the cell. It is composed of lipid bilayer. Proteins are embedded into the plasma membrane. Carbohydrate is present in the form of glycoprotein. The protein part of the plasma membrane has many receptors that bind to various signaling molecules. The signaling molecules are chemical substances like hormones, neurotransmitters, or growth factors, which are responsible for activating several signal transduction pathways.

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait? (4 pts)? 12pt v R Paragraph V BIU A श्र > B
