The gene that controls the Duffy blood type is D (affected D is dominant to d) and the gene that controls the Lamelar Cataract gene is L (wildtype L is dominant to the recessive affected l). These are separated by 30 map units, so recombination occurs 30% of the time. Matt and his partner are heterozygotes for both of these genes. Both Matt's chromosomes are in trans while his partners are in cis. What is the probability that they will have offspring without the Duffy blood type, but affected by cataracts?

Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
