Bats with the B allele OR the S allele suck blood. But bats who are bbss don't suck blood. You cross two blood-sucking bats, and notice that 15/16 of their offspring suck blood, and 1/16 don't. a) (1) What were the genotypes of each parent? (Hint: see the text fig 3.21) b) (2) If you take one of the parents (whose genotype you figured out in part a), and test cross the parent (i.e. mate that parent to -well, you know what a test cross is, right?), what ratio of blood suckers to nonblood suckers will you get

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
