When two strains (tropical and temperate) of the nematode Caenorhabditis briggsae are crossed, they exhibit a difference in allele inheritance in different environments (depending on temperature). We suspect that tropic C. briggsae grow optimally at 25 C, while temperate C. briggsae grows optimally at 20 C. When growing the HK104 (temperate) and AF16 (tropic) hybrids, it was previously observed that at 20 C more offspring had HK104 alleles, and at 25 C more offspring had AF16 alleles.

The goal of my project is to investigate whether this phenomenon is present only in the AF16-HK104 hybrids or whether this trend persists in other tropic x temperate C. briggsae. To confirm this pattern, VT847 (tropic) and HK105 (template) hybrids will be created to analyze whether or not they exhibit the same pattern.
