| Abstract: | Heritabilities of egg size (0.7 ± 0.2), hatch weight (0.5 ± 0.1), chick viability (0.3 ± 0.2), and body weight at 75 days of age (0.6 ± 0.1) are given for Red Grouse (Lagopus lagopus scoticus). Much of the variation in mean egg size amongst wild hens within years was due to inherent differences amongst hens and had little to do with differences in their environment. Cocks had no detectable effect on the egg size of their mates or the hatch weight and viability of their chicks, but did affect their chicks' body weight. It seems that egg size in Red Grouse is determined largely by inherited factors and in turn affects hatch weight and viability. |
