Drosophila: Developmental rate of Drosophila melanogaster

In glmtoolbox: Set of Tools to Data Analysis using Generalized Linear Models

Developmental rate of Drosophila melanogaster

Description

Drosophila melanogaster developmental stages were monitored as part of an experiment to determine the effect of temperature on their duration. The eggs were laid at approximately 25 degrees Celsius and remained at that temperature for 20-30 minutes. The eggs were then brought to the experimental temperature, which remained constant throughout the experiment.

Usage

data(Drosophila)

Format

A data frame with 23 rows and 3 variables:

Temp

a numeric vector indicating the temperature, in degrees Celsius.

Duration

a numeric vector indicating the average duration of the embryonic period, in hours, measured from the time at which the eggs were laid.

Size

a numeric vector indicating how many eggs each batch contained.
