Allele for gray fur is A (dominant)
  Allele for white fur is a (recessive) 
Genotype of heterozygous is Aa (heterozygous is gray, because its allele is dominant) 
If we cross two heterozygous 
<span>Parents: Aa  x  Aa
</span> <span>F1: AA  Aa  Aa aa</span> 
The ratio between phenotypes is 3:1 (gray:white) 
<span>AA Aa Aa  are with gray fur</span> 
<span>aa is with white fur </span>

There<span> are many plant-</span>like protists<span>, such as algae, that get </span>their<span> energy from sunlight through photosynthesis. Some of the </span>fungus-like protists, such as the slime molds decompose decaying matter. The animal-like protists<span> must "eat" or ingest </span>food<span>.</span>
