Mendel also studied tall and short varieties of pea plants. When he crossed tall x short plants together, the F1were tall. The tall F1 plants were self-hybridized to produce the F2. What proportion of phenotypes would be expected in the F2?

Describe how Gregor Mendel tested his pea plants to show that they were true-breeding before he began his experiments.

Two genes are found in a chameleon, one for camouflage (dull colors dominant to vibrant colors) and another for muscle strength (strong dominant to weak), which seem to follow basic Mendelian inheritance patterns. To determine if they are linked, you set up a testcross and got the following results: Phenotype Dull colors; Strong Dull colors; Weak Number of Progeny 98 76 Vibrant colors; Strong 72 Vibrant colors; Weak 105 Did you start this experiment with the genes in coupling or repulsion? (Be sure you know how to run the chi-square based off this information as well!) O Coupling O Cannot determine with this information O Repulsion

Examine the following crosses carried out to explore inheritance of traits in pea plants. Parent cross: rough, soft peas X smooth, hard peas F1 : all rough, hard Test cross: rough, hard X smooth, soft peas F2 : 115 rough soft, 110 smooth hard, 8 rough hard, 12 smooth soft Identify which traits are dominant, and either support or refute the hypothesis that the traits rough/smooth and soft/hard assort independently according to Mendel's law.
