In monkeyflower, an allele for yellow flowers (Y) is dominant over an allele for white flowers (y). At an independently assorting locus, an allele for entire petals (E) is dominant over an allele for fringed petals (e). A plant that is homozygous for yellow and entire petals is crossed with a plant that is white and fringed. A resulting F1 plant is then crossed with a plant that is white and fringed, and the following progeny are produced:
10 yellow and entire
15 yellow and fringed
50 white and entire
25 white and fringed
Use a chi-square test to compare the observed numbers with the expected numbers from the cross.
The value for the chi-square test statistic is:
1
15
38
53
