Reading
RL 8.1: Cite textual evidence that most strongly supports an analysis of what the text says explicitly as well as inferences drawn from the text.
RL 8.4: Determine the meaning of words and phrases as they are used in a text; analyze the impact of specific word choices on meaning and tone, including analogies or allusions to other texts.
RI 8.6: Determine an author’s point of view or purpose in a text and analyze how the author acknowledges and responds to conflicting evidence or viewpoints.
Math
NC.8.SP.4 Understand that patterns of association can also be seen in bivariate (depending on 2 variables) categorical (classification) data by displaying frequencies and relative frequencies in a two-way table.
Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects.
Use relative frequencies calculated for rows or columns to describe possible association between the two variables.

The principles of genome mapping and gene discovery. In a few cases, the genes that control genetic variation between animals have a large enough effect to be individually recognizable, such as the sex-linked.
Dwarf gene in the chicken. Usually this is not the case for traits such as growth and fertility, which are traits controlled by many genes. The trait-genes that control these quantitative traits are located at quantitative trait loci (QTL). The chicken genome contains approximately 30,000 genes distributed over thirty-nine pairs of chromosomes. QTL mapping is the first stage in the discovery process of identifying the trait-genes at these loci (Figure 2).
QTL can be located in the genome through associations between performance and the inheritance of genetic markers in a suitable pedigree (Hillel, 1997). The key to this process is a map of genetic markers evenly spaced throughout the genome (Georges and Anderson, 1996).
- Reliable definition of trait
- Identification of genetic resources
- Low resolution mapping of QTL
- Identification of candidate-genes
- Casual relationship between and trait
