Start with the p generation with the following genotypes (aa x aa). based on classical mendelian inheritance, how will a cross between two homozygous parents, one dominant and one recessive, influence future generations? a) the f1 generation will show an even split between the dominant phenotype and the recessive phenotype.   b) the f1 generation will all show the dominant trait and future crosses will continue to produce genotypes expressing the dominant trait.   c) although the f1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.   d) the f1 generation will show a mix of the dominant phenotype and recessive phenotype and over generations the recessive trait will increase in number.

idk and i also need to know where are those bio brainy acts lol

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
