The process of evolution involves changes in the genetic makeup of a population over a period of time. Sexual reproduction enhances variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, while others can be harmful and hinder survival. In this experiment, students mimicked random mutations. The mutations affected eyesight and appendages. Data was collected by the students to determine if the mutations were helpful or harmful when trying to collect and eat food.

Question

The process of evolution involves changes in the genetic makeup of a population over a period of time. Sexual reproduction enhances variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, while others can be harmful and hinder survival. In this experiment, students mimicked random mutations. The mutations affected eyesight and appendages. Data was collected by the students to determine if the mutations were helpful or harmful when trying to collect and eat food.

Based on the phenotypic results of the mutations, select the group or groups that would be LEAST LIKELY to survive?

A Groups B and D
B Groups D and G
C Groups F and G
D All groups other than C

Answer 1

D All groups other than C

Explanation: Since mutations can be helpful or harmful, the group with mutations that are least likely to survive would be all groups other than C, as they may have a higher likelihood of having harmful mutations that hinder survival. Group C would be the least likely to be at a disadvantage as they may have beneficial mutations that enhance survival.
