Geospiza is a genus of finches that inhabit the Galapagos İslands. In 1976, finches were grouped together based on the average depth of their bills. The data from the first generation of grouped finches are plotted on the X-axis. The bill depths of the offspring from each group are plotted on the Y-axis. In 1978, the experiment was repeated after a drought on the Galapagos Islands. The red line represents the data from 1976 and the blue line represents the data from 1978. The slope of both the red line is 0.90 and the slope of the blue line is 0.90. Was there any change in the heritability of the bill depth trait after the drought? Explain your reasoning.

Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.

Midparent bill depth (mm)
Geospiza is a genus of finches that inhabit the Galapagos Islands. In 1976,
finches were grouped together based on the average depth of their bills. The
data from the first generation of grouped finches are plotted on the X-axis. The
bill depths of the offspring from each group are plotted on the Y-axis. In 1978,
the experiment was repeated after a drought on the Galapagos Islands. The red
line represents the data from 1976 and the blue line represents the data from
1978.
The slope of both the red line is 0.90 and the slope of the blue line is 0.90. Was
there any change in the heritability of the bill depth trait after the drought?
Explain your reasoning.
