Females from a pure-breeding curly-winged strain are mated with males from a pure-breeding straight-winged (wild-type) strain. The F1 mate with each other to produce an F2 generation that consists of 160 flies with curly wings and 80 with straight wings. What can you infer from this observation? Explain your answer and why the other options do not qualify,  A) Curly wings is a recessive trait.  B) The dominant curly wing allele is also a recessive lethal.  C) Wing shape is controlled by two codominant alleles.  D) Two interacting genes determine wing shape.  E) All of the hybrid F 1 flies had straight wings.

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.
