gametes have half the amount
Answer:
Bridgham et al. (2006) showed that the interaction between a steroid hormone (aldosterone-M) and its receptor (mineralocorticoid) evolved by Darwinian gradualism. In this work, the authors demonstrated a primitive affinity between the hormone and its receptor that was initially present in chemically similar but more ancient ligands. This result has implications in understanding the association between gene duplication and the evolution of hormone signaling pathways. For example, in invertebrates, this work reinforces the importance of gene duplication in the existing interaction between paralogous glucocorticoid receptors and their receptor mineralocorticoid genes that were derived from duplication (Thornton 2001).

Absolute monarchy hold the supreme or absolute power, while in a constitutional monarchy the head of state is a hereditary or elected monarchy. in other words the king or queen of the absolute monarchy is a dictator.
Answer:
White fur is only an evolutionary advantage if the creature can hide in snow.
If you live in a temperate forest biome and want to hide from enemies, you wouldn't want fur that sticks out brightly against the dark forest.
Just like, if you lived in a snowy biome, you wouldn't want black fur that would stick out against all the snow.
So no, white fur is not an evolutionary advantage in a temperate forest biome
Hope this helps!
