Both parents produce 25% each of SY, Sy, sY, and sy. Study with Quizlet and memorize flashcards containing terms like A family tree that describes traits in families is called a __________. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. Discoveries in fruit fly genetics can be. a tool scientists use to investigate the possible combinations of genetic crosses. Study with Quizlet and memorize flashcards containing terms like Phenotypes whose inheritance is consistent with Mendel's. If we complete the cross, we find that the possible offspring can only be Bb. hermione pregnant and alone fanfiction The mathematical chance of a specific outcome in relation to the total number of possible outcomes. (Review the tutorials for problems #1 and problem #4 if necessary). Use a Punnett square to predict the traits of the offspring for a cross between two parents, one homozygous dominant and one homozygous recessive.
