Good Genes x Environment

Animal husbandry resources

Attractive male displays may advertise “good genes,” resulting in high quality offspring for females that prefer such displays.  How does environmental variation affect the relationships between male displays, “good genes,” and offspring fitness?

We are investigating how “good genes” advertised gray tree frog call duration interact with the environment to influence offspring fitness.  Our goals are to determine (1) the relationship between male call duration and offspring fitness in different environments, (2) the degree to which call duration of fathers predicts call duration of their sons, and how environment and genotype together influence call expression, and (3) how genotypes and condition influence the allocation of resources to reproduction.
