Assume that a cross is made between a heterozygous tall pea plant and a homozygous short pea plant. Fifty offspring are produced with 30 tall and 20 short plants. A genetics student hypothesizes that the data fit a ratio of 1:1 and wants to test the hypothesis by performing a chi-square analysis. Should the hypothesis be accepted or rejected? Why?

A) should be accepted, p value is greater than 0.05

B) should be accepted, p value is smaller than 0.05

C) should be rejected, p value is greater than 0.05

D) should be rejected, p value is smaller than 0.05

Answer #1

A. The hypothesis should be accepted as the calculated p value is greater than p=0.05 and the deviations that are observed are by chance.

The necessary calculations are given below.

Which of the following correctly describes this cross? Choose all that apply. Now determine the genotypes of the possible gametes and set up a Punnett square for the cross between two double heterozygotes, as you did before in a previous question (no need to attach that Punnett square). From your Punnett square, determine how many individual kernels have the genotypes and phenotypes shown in the table below. Enter your answers as a number (e.g. 7) not a word (e.g. seven)...

The expression of yellow petals in sunflowers is due to the dominant allele Y. The homozygous recessive (y) has orange petals. Plant height is controlled by another gene with two alleles, T and t, with Tall (T) being dominant to short (t). Two individuals that are heterozygous for both traits are crossed, the number of offspring of each phenotype is recorded in the table below. 1. The assumption is that these two genes assort independently. To test this, complete a...
