Spotted lanternfly females were crosses with males possessing short wings (sw) ebony body (e) and sephia (s) eyes, which are recessive traits. 1000 offspring were counted, and the results are shown in the table below. No determination of sex was made. Using proper notation determine the linkage-genotype of the female parent. Determine the sequence of the three genes and map the distances between them. Calculate the COC and interference in the cross and describe what it means. Phenotype + + e S SW + s + + + sw e + + + S SW e s+e + SW + #offspring 332 331 111 121 46 56 7 6

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.
