Over generation, female reindeer in a Finnish population give both 2 larger of offspring. which type of selection is occurring n how would a distrubution curve 4 dis trait change over time?

Question

A ) Stabilizing selection; da curve would b taller in da middle

B ) Directional selection; da curve would shift 2 da left

C ) Directional selection; da curve would shift 2 b da rigth

D ) Stabilizin selection; da curve would become shorter in da middle

Answer 1

Based on the information you've provided, it seems that female reindeer are producing larger offspring over generations. This indicates a preference or advantage for larger offspring, which suggests that directional selection is occurring.

In directional selection, one extreme phenotype (in this case, larger offspring) is favored over others. Consequently, the distribution curve for the trait (offspring size) would shift towards that favored phenotype.

Given your options:

C) Directional selection; the curve would shift to the right.

This option aptly describes the process of directional selection where, over time, the average size of offspring would increase, leading to a shift in the distribution curve to the right.
