Question

bb or ee are examples of:
dominant traits only
heterozygous
homozygous
recessive traits only

Explanation:

To determine what Bb or Ee represent, we recall genetic terminology:

• Heterozygous means having two different alleles (e.g., B and b, E and e) for a gene.
• Dominant traits only would involve alleles like BB (dominant homozygous), not Bb.
• Homozygous means having two identical alleles (e.g., BB or bb, EE or ee).
• Recessive traits only would involve alleles like bb (recessive homozygous), not Bb.

So Bb and Ee are heterozygous.

Answer:

The correct option is the one labeled "Heterozygous" (the second option from the top among the choices).
