Question

genetic factors and growth quick check
which example best describes the influence of genetic factors? (1 point)
a shrub with good access to sunlight is taller than other shrubs located in shaded areas.
a com plant is the same height as another com plant of a different variety.
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.
the adult offspring of a pair of deer is shorter than its parents and obtained fewer nutrients when it was younger.

Explanation:

Genetic factors are related to the inheritance of traits from parents. In the case of the horse, its size being similar to its parents and other horses of the same breed indicates genetic influence. The first option (shrub height due to sunlight) is an environmental factor. The second option (corn plant height of different varieties) doesn't clearly show genetic influence as it's about different varieties. The fourth option (deer offspring shorter due to nutrients) is an environmental (nutrient - related) factor.

Answer:

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.
