Select the phrase to complete the sentence:
The first albino deer born in a population was most likely due to a mutation in the DNA of a gamete.
Explanation:
1. When an albino deer is born, it means that the deer lacks pigmentation, resulting in a white or pale appearance.
2. Albino individuals inherit a genetic mutation that affects the production of melanin, the pigment responsible for skin, hair, and eye color.
3. The mutation responsible for albinism occurs in the DNA of a gamete, which is a reproductive cell (sperm or egg). This mutation is then passed on to the offspring.
4. In the case of the albino deer, the mutation in the DNA of a gamete led to the offspring being albino, as the genetic information for producing melanin was altered.
5. This genetic mutation is not caused by exposure to chemicals, environmental changes after birth, or a mutation in a parent body cell.
Therefore, the most suitable phrase to complete the sentence would be "a mutation in the DNA of a gamete."
