Concept explainers
a.
To determine: The diagram of the chromosomes of the parents, the hybrid, and the tester.
Introduction: Crossover or synapsis in Meiosis is where the ends of the homologous chromosomes exchange genetic information in the form of alleles to create various genetic combinations.
b.
To determine: The diagram of the crossover necessary to produce the desired genotype.
Introduction: In genetic algorithms and evolutionary computation, crossover, also called recombination, is a genetic operator used to combine the genetic information of two parents to generate new offspring.
c.
To determine: The percentage of the testcross progeny will be of the phenotype that she needs.
Introduction: A test cross, first introduced by Gregor Mendel, involves the breeding of an individual with a phenotypically recessive individual, to determine the zygosity of the former by analyzing proportions of offspring
d.
To determine: The assumptions that can be made
Introduction: Genetic recombination is the exchange of genetic material between different organisms which leads to the production of offspring with combinations of traits that differ from those found in either parent.

Introduction To Genetic Analysis
- series of two-point crosses were carried out among six loci (a, b, c, d, e and f), producing the following recombination frequencies. According to the data below, the genes can be placed into how many different linkage groups? Loci a and b Percent Recombination 50 a and c 14 a and d 10 a and e 50 a and f 50 b and c 50 b and d 50 b and e 35 b and f 20 c and d 5 c and e 50 c and f 50 d and e 50 d and f 50 18 e and f Selected Answer: n6 Draw genetic maps for the linkage groups for the data in question #5.
