Question

1. what will be the phenotype of the fly that grows from the fertilized cell shown below? allele key dominant c - curly wing b - brown body l - legs on head r - red eyes recessive c - normal wing b - black body i - antenna r - orange eyes normal wings, black body, antenna, and red eyes. curly wings, brown body, legs on head, and red eyes. curly wings, brown body, legs on head, and orange eyes. normal wings, brown body, legs on head, and red eyes.

Explanation:

Step1: Analyze wing trait

The alleles for wings are \(c\) and \(c\). Since \(c\) is recessive (normal wing), the wing phenotype is normal wing.

Step2: Analyze body trait

The alleles for body are \(b\) and \(b\). Since \(b\) is recessive (black body), the body phenotype is black body.

Step3: Analyze head trait

The alleles for head are \(l\) and \(l\). Since \(l\) is recessive (antenna), the head phenotype is antenna.

Step4: Analyze eye trait

The alleles for eyes are \(R\) and \(R\). Since \(R\) is dominant (red eyes), the eye phenotype is red eyes.

Answer:

Normal wings, black body, antenna, and red eyes.
