? Values of families selected to begin next generation Values of all other families Family mean for female flower size Figure 1 For each family, trait values are plotted in a two-dimensional grid. The x-axis shows the mean calyx widths of female flowers, and the y-axis shows the mean calyx widths of male flowers. The diagonal line without arrows shows the regression line. This is also the major axis line. Perpendicular to the regression line (with arrows) is the minor axis line. Question 1. Why must family selection, not individual selection, be used when trying to change the genetic correlation between male and female traits? Question 2. Is the correlation between male and female flower calyx width in the figure above positive or negative, strong or weak? Question 3. What do you notice about the selected families in relation to the regression/major axis line? Relative to the non-selected families, what can be said about the mean male calyx widths of male flowers in the selected families?Explanation / Answer
Answer 1) since genetic correlation occurs when single gene affects two traits.And for genetic correlation there must be atleast 2 members. That's why family slection is used to change genetic correlation.
Answer 2)positive and weak
Answer 3)
