You sample 1500 dung beetles in a population for 2 alleles A1 and A2 and get the following data: A1A1 825 individuals A1A2 525 individuals A2A2 135 Individuals Is this population in Hardy Weinberg Euilibrium, use a chi square test to determine?
The flowers of 4 o’clock plants may be red, pink or white. Reds crossed to whites only produced pink offspring. When pink flowered plants were crossed with each other, they produced 113 red, 129 white, and 242 pink. It is hypothesized that these colors are controlled by a single gene pair of incompletely dominant alleles. Is this hypothesis acceptable on the basis of a Chi-square test? Show your solutions below.
The British Department of Transportation studied to see if people avoid driving on Friday the 13th. They did a traffic count on a Friday and then again on a Friday the 13th at the same two locations. The data for each location on the two different dates is in the table. Do the data show that on average fewer people drive on Friday the 13th? Test at the 5% level.Traffic Count Dates 6th 13th 1990, July 137669 135825 1990, July 129699 128891 1991, September 136898 138275 1991, September 138966 139940 1991, December 132021 129640 1991, December 119268 119214 1992, March 131938 131104 1992, March 123306 124760 1992, November 129499 129219 1992, November 138568 135934
Mendel counted 4000 peas from a dihybrid cross and predicted a 9:3:3:1 phenotypic ratio with the following results. Yellow and smooth peas 2100; yellow and wrinkled peas 700: green and smooth peas 859 and green and wrinkled peas 341. Support or refute these data with a CHI-Square analysis. State the Null hypothesis and its outcome for this set of data.
Below are F2 results of two of Mendel's monohybrid crosses. State a null hypothesis to be tested using x2 analysis. 11. Full pods (dominant) 904 constructed pods (recessive) 276 12. violet flowers (dominant) 717 white flowers (recessive) 213
