Which of the following describes a genotype?
What's in your genes
What you physically look like
Which of the following describes a phenotype?
What's in your genes

WHY are there 2 alleles for 1 trait?
Because you inherit 1 from each parent
Because when the DNA replicates, it makes a second copy of the allele
Because when cells undergo mitosis, they make 2 alleles as they make 2 alleles
Because you have 2 phenotypes for every trait
