In Drosophila, red eyes is a wild-type phenotype. Several different genes affect eye color. One allele causes purple eyes, and a different allele causes sepia eyes. Both of these are recessive to red eye color. When flies with purple eyes were crossed to flies with sepia eyes, all F1 flies had red eyes. When the F1 offspring were allowed to mate, the F2 flies were as follows: 162 purple eyes 172 sepia eyes 58 purplish sepia eyes 478 red eyes...

A researcher wanted to examine if there is a relationship between color preference (le, favorite color red, yellow, green or blue) and personality type (ie, extrovert or introvert). He selected a sample of n = 200 participants, each participant took a personality test and identified the favorite color. The collected data are shown in the table below. Do the data indicate a significant relationship between personality type and color preference? Test with p<.01. YELLOW GREEN BLUE RED 10 90 INTROVERT...

40. Pink-eye and albino are two recessive traits found in the deer mouse Peromyscus maniculatus. In pink-eyed mice, the eye is devoid of color and appears pink because of the blood vessels within it. Albino mice are completely lacking color, both in their fur and in their eves. F. H. Clark crossed pink-eyed mice with albino mice; the resulting Fi had normal coloration in their fur and eyes. He then crossed these Fį mice with mice that were pink eyed...
