You are studying the amino acid sequence of a protein shared by four organisms. You want to know which organism is most closely
related to organism A. You have data that shows the number of amino acid differences between organism A and each of the other organisms. Study the data in the chart and use it to answer the question.
Well, I need the chart first of all, but second, If you have to find out which one is closely related to A, just take the amino acid sequence and compare the sequence to each organism, and which ever one has the most related sequences, is the closely related organism.
An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
