"in a population of 100, 65 of the people are homozygous dominant and 15 are homozygous recessive. what is the genotypic frequency of the homozygous dominant population, heterozygous population and homozygous recessive population.

Its easy to get the genotypic frequencies as follows;

1.       Homozygous dominant;

65/100 = 0.65

2.       Homozygous recessive;

 15/100 = 0.15

3.       To get heterozygous population;

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
