4 Topic 1 Question Explain what pure recessive, pure dominant and hybrid are:

5 Pure recessive: an allele that is masked when a dominant
allele is present. Pure dominant: an allele whose trait always shows up in the organism when the allele is present Hybrid: An organism that has 2 different alleles from a trait Topic 1 Answer
