Ihave some biology questions. best and fastest answer gets brainliest! what does homozygous mean? what does heterozygous mean? know how to complete monohybrid and dihybrid crosses. explain the 4 types of chromosomal mutations. explain the 2 types of gene mutations. what are non-disjunction mutations? what are mutagens? how can they affect a person? what happens if a mutation is in a gamete? (i have a ton of points so giving out this many is nothing. answer seriously or i will report your answer. i need answer by tomorrow.)
