<h2>Answer and Explanation </h2>
The genetic recombination is a biological process in which the recombination of homologous DNA strand occurs. There are three types of genetic recombination in human being that is :
Human Reproducation that is by introducing new gene combination to the population.
By cell Mutation is it  that is changes in the DNA.
By Gene flow it is that is by movement of a gene from one population to another population.

Answer:
The "short tail" dominant allele is easier to eliminate by selective breeding.
Explanation:
The only way for a recessive allele to be expressed (be visible) is when it appears as recessive homozygotic. These means the organisms need to have 2 copies of the gene. Selective breeding is based on the characteristics that one can see, so if the organism shows the "dilute" phenotype you can keep reproducing this individuals and get rid of the dominant allele.
On the other hand if you have a population with the dominant phenotype, you discard all the ones that have a recessive trait and you breed the dominant phenotype you could still get individuals with the recessive phenotype and individuals that express the dominant phenotype but are heterozygous. 
 
        
             
        
        
        
Answer:  Histology is the study of the microscopic anatomy of cells and tissues of plants and animals. It is performed by examining a thin slice (section) of tissue under a light microscope or electron microscope.
