Two crosses were made in Neurospora involvingthe mating type locus and either the ad or p genes.In both cases, the mating type locus (A or a) was oneof the loci whose segregation was scored. One crosswas ad A × ad+ a (cross i), and the other was p A × p+ a(cross ii). From cross i, 10 parental ditype, 9 nonparental ditype, and 1 tetratype asci were seen.From cross ii, the results were 24 parental ditype,3 nonparental ditype, and 27 tetratype asci.a. What are the linkage relationships between themating type locus and the other two loci?b. Although these two crosses were performed inNeurospora, you cannot use the data given tocalculate centromere-to-gene distances for anyof these genes. Why not?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
