You observe that 50% of the offspring of a two-locus mapping cross are recombinant.  You could conclude that Group of answer choices Crossing over never occurs between these two loci. The two loci are so far apart on the same chromosome that a crossover even occurs between them in every meiosis. Either the two loci are on separate chromosomes or they are so far apart on the same chromosome that a crossover even occurs between them in every meiosis. The two loci are on separate chromosomes. None of these statements is likely to be true.

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.
