Question
A cross between two organisms with this characteristic results in 75% of the offspring having the dominant phenotype. For 10 points each:
[10m] Name this characteristic where organisms have two different alleles of a gene. Organisms with this characteristic are notated as having one uppercase and one lowercase letter.
ANSWER: heterozygotes [accept heterozygous]
[10e] The archetypal organism studied in genetic inheritance is this plant grown by Gregor Mendel. The green variety of this vegetable grows in pods.
ANSWER: peas [accept specific answers like green peas, accept Pisum sativum]
[10h] Deviations from the phenotypes expected in Mendelian genetics can be due to this phenomenon. Elements close together on a chromosome undergo this phenomenon, which can be used to map a chromosome’s contents.
ANSWER: genetic linkage [accept gene linkage; prompt on partial answers; prompt on crossing over]
