The assessment instruments were designed to measure students' interrelated understandings of genetics and their ability to solve and interpret problems using Punnett square diagrams. Regression analyses were conducted to examine the predictive influence of meaningful learning orientation, reasoning ability, ...
When a person inherits one (t) from the father and then one (t) from the mother, the recessive alleles (tt) are inherited and the person can not roll their tongue. As can be seen in thePunnett squareabove, this would happen approximately twenty-five percent of the time. (Note that th...
version of a trait might appear to be dominant. Overall, applied to modern Mendelian problem solving, the results of Weldon’s experiments present dominance as a contextually relative relationship rather than a permanent characteristic of an allele (Jamieson and Radick2013). It is interesting to not...
This study explored factors predicting the extent to which high school students ( N = 140) acquired meaningful understanding of the biological topics of meiosis, the Punnett-square method, and the relationships between these topics. This study (a) examined mental modeling as a technique for ...
