Question

5 which offspring could not arise from the parent cells with the chromosomes shown below? assume crossovers can occur between chromosome pairs in the parent cells. allele key dominant c - curly wing b - brown body l - legs on head r - red eyes recessive c - normal wing b - black body l - antenna r - orange eyes offspring a offspring b offspring c offspring d

Explanation:

• Parent 1 has alleles for \(L\) (legs on head) and Parent 2 has alleles for \(l\) (antenna).
• Offspring inherit alleles from parents. For an offspring to have antenna (\(ll\)), it must get \(l\) from both parents.
• Offspring C has antenna (\(ll\)), normal wings (\(cc\)), brown body (\(BB\)) and red eyes (\(RR\)).
• Parent 1 has \(B\) (brown body) and \(L\) (legs on head), Parent 2 has \(b\) (black body) and \(l\) (antenna).
• Offspring C cannot get \(l\) from Parent 1 (Parent 1 has \(L\) not \(l\)) to have \(ll\) (antenna) along with \(BB\) (brown body).

Answer:

Offspring C
