In corn the genes for tassel length (alleles T and t) and rust resistance (alleles R and r) are known to be on separate chromosomes. In the course of a routine mating check experiment, a breeder got the following results upon crossing T/t:R/r with a double recessive strain (t/t;r/r): genotype Number of progeny T/t; R/r 98 t/t; r/r 104 T/t; r/r 3 t/t; R/r 5 In addition to these data she noted that the cobs contain only about 50% of the expected kernels. Note that in corn, each kernel is the result of one mating or can be considered one progeny. Hence 50% of the matings are not producing viable offspring. Draw a diagram showing the arrangement of the alleles on the parental chromosomes. Based on your hypothesis from part b, reassign genotypes to the progeny classes. Enter your new genotypes into the table above as an additional column. If the karyotype was done on the progeny what unusual feature would be observed?

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.
