What are the learning objectives for Lab 2?
Give this one a try later!
- Genetic linkage occurs between genes that lie so close together on a
chromosome that their alleles are unable to assort independently as predicted
by Mendel.
- Genetic linkage produces significantly more progeny with parental phenotypes
and significantly fewer progeny with non-parental phenotypes than are
expected by random chance.
- The mechanism of crossing over between homologous chromosomes results in
,recombination of alleles on chromosomes.
- Recombination, as a result of crossing over, creates substantial new
genetic diversity favored by evolution and randomizes the arrangement of
alleles of linked genes on chromosomes.
- Design Dihybrid Crosses for detection of Linkage.
- Understand the terms associated with Linkage, Complete Linkage,
Incomplete Linkage, Sex-Linkage, and Chromosome Location.
- Understand Configuration and how it effects gamete formation.
- Understand the basic attributes of Drosophila melanogaster
- Conduct crosses and collect progeny data using the fly portal
- Design and diagram monohybrid crosses
- Complete chi-squared analyses to compare observed versus expected traits
- Better understand the effects of different progeny number (sample size)
on expected ratios
- Understand the terms associated with multi-trait crosses.
- Design and diagram crosses involving two or more traits.
- Use the Electronic Fly Colony to perform multi-trait Mendelian crosses.
- Identify segregation and assortment ratios for progeny data.
- Use the Product Rule to generate assortment ratios from segregation
ratios.
- Confirm assortment ratios using Chi-Squared analysis.
- Determine probabilities for genetic outcomes.
- Work Mendelian dihybrid word problems with confidence.

Definition
Neither allele is dominant over the other. Instead, the resulting F1
phenotypes appear as a blending of the two parental phenotypes.
