2.give two examples of plants that have been developed through selective breeding techniques
3. examine the following pedigree
a. what can you deduce about the pattern of inheritance of the trait?
b. give one example of a human genetic condition that is passed on in this way.
c. what is the genotype of Individual I-1?
d. how do the phenotypes of individual III-1, III-2, and III-3 differ from the predicted ratios? what might account the difference?
4. you discovered a new autosomal recessive genetic condition. individuals with this condition do not survive long after birth, and so do not have children of their own. will the trait be eliminated from the population over time? explain.
