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.
