Expert Solution

Summary Introduction

To draw: A map for bacterial chromosome.

Introduction: The bacterial chromosome is transferred during the process of conjugation, which leads to genetic recombination. The genetic recombination provides data for mapping.

Answer to Problem 1NST

Pictorial representation: The sequence of genes are arranged as contigs, and their overlapping is shown in fig 1.

Concepts of Genetics (11th Edition), Chapter 6, Problem 1NST , additional homework tip 2

Explanation of Solution

The transfer of chromosome is strain specific. It also depends on where and in which orientation in the chromosomes the F factor has integrated.

In interrupted mating, there is difference in the time of gene transfer. Some may be transferred earlier while other are transferred late. In strain 2 and 4, the common sequence is MB. In strain 1 and 3, CHRO is common, and HRO is the repetitive sequence.

Summary Introduction

To determine: Whether the given data support the concept of circularity.

Introduction: A single bacterial chromosome contains most of the DNA of the bacteria. Mapping the bacterial chromosomes provides information regarding the position of various genes.

Explanation of Solution

Contigs are the continuous set of overlapping DNA segments. These segments represent a particular region of the DNA. In the given figure, the end overlaps each other. In two strains the order is reversed which means the orientation of the transfer is reversed. By the overlapping of the contigs in the given strains, the map that will be constructed is TCHROMBAK. All the genes are linked together to give a map. The ends overlap indicates that the map is circular. When all these chromosomes are arranged in the form of a map, they form a circular map.

Thus, the map constructed that will be constructed from the given Hfr strains is TCHROMBAK. The overlap ends indicate that the map is circular.

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?
