The genes kn-1 (produces leaves with small "knots") and d3 (causes dwarfed stature) are 40 map units apart on chromosome 1 of corn. the distance between these two loci was determined using a corn line with no known inversions on chromosome 1. a paracentric inversion of 20 map units lies between (but not containing) kn-1 and d3 in popcorn lines. if the distance between the two loci was mapped using a heterozygote with one normal chromosome 1 and one paracentric inversion chromosome 1, what is the apparent distance between the two loci?

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.
