Here are the examples again, with discussion:
A horse is the same size as its parents and similar height to other horses of the same breed that it lives with on a farm.
- This is an example of genetic influence because the size and height of the horse are likely to be similar to its parents due to inheritance, and breed characteristics are determined genetically.
A corn plant is the same height as another corn plant of a different variety.
- This example does not necessarily show genetic influence because the two corn plants are of different varieties; thus, similarities in height might be due to similar growing conditions rather than genetics.
A shrub with good access to sunlight is taller than other shrubs located in shaded areas.
- This is an example of environmental influence (access to sunlight) affecting the height of the shrubs, rather than genetic factors.
The adult offspring of a pair of deer is shorter than its parents and obtained fewer nutrients when it was younger.
- This also looks at environmental influence (nutrient availability) rather than genetic factors since the shorter height could be due to poor nutrition rather than inherited traits.
The most appropriate example for genetic factors would be the first one:
"A horse is the same size as its parents and similar height to other horses of the same breed that it lives with on a farm."
Reason: Genetic factors contribute to the horse being of the same size and height as its parents, and breed characteristics are also a result of genetic information passed down through generations.
"A horse is the same size as its parents and similar height to other horses of the same breed that it lives with on a farm."
This example indicates that the horse's size and height are inherited traits that are influenced by its genetic makeup, which it shares with its parents and other horses of the same breed.
