MULTIPLE CHOICE QUESTION

In pea plants, the tall (T) allele is dominant to the dwarf (t) allele. Two heterozygous (Tt) pea plants are crossed and produce 400 offspring. Three hundred offspring are expected to be tall, and 100 are expected to be short. There hundred offspring are expected to be tall, and 100 are expected. There are 290 tall offspring observed and 110 dwarf off spring observed. Calculate the chi-square value from this data (using a p-value of 0.05), and state whether there is likely a statistically significant difference between the observed and expected data.

The chi-square value is 0.67. There is a statistically significant difference between the observed and expected date.

The chi-square value is 0.67. There is NOT statistically significant difference between the observed and expected data.

The chi-square value is 1.33 . There is statistically significant difference between the observed and expected data.

The chi-square is 1.33. There is NOT a statistically significant difference between the observed and expected data.
