THEME: Interactions between non-allelic genes. Pleiotropy. Expressivity. Penetrance.
Task 1. Solve the tasks that modeling interaction between non-allelic genes.
1. Height is quantitative (polygenic) trait in humans. Height is controlled by three pairs of genes,
located in different chromosomes. A very tall person has 6 recessive genes (alala2a2a3a3) and
very shot person has 6 dominant genes (A1A1A2A2A3A3). What is the genotype of a medium-
height person?

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research.b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research.c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)
