The variation of kernel color in corn plants is an inherited trait. r is the dominant allele for red kernels in a corn plant and r is the recessive allele for yellow kernels. what is the probability that a corn plant with the genotype rr crossed with a corn plant rr will have offspring with the genotype rr? express your answer as a fraction using numerals for numbers and / for the fraction bar.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
