Summary Introduction

Introduction: A virus is an infectious agent that cannot be seen through the naked eyes. Virology is the study of viruses and virologists are the biologists who study viruses. Viruses are obligate intracellular parasites because it needs a living host cell for replication. Obligate intracellular parasites do not have the ability to reproduce outside their host cell.

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
