<span>A prokaryote is a unicellular organism that belongs to either the domain Bacteria or the domain Archaea. Therefore, unlike a eukaryote, the prokaryote lacks in a nucleus and other organelles. The first organisms that appeared about 3.5 billions years ago were prokaryotes. They developed primitive forms of photosynthesis without oxygen as a waste. The first photosynthesizing prokaryotes appeared about 2.7 billion years ago which led to the changes in Earth atmosphere and consequently organisms dependant on oxygen could arise.</span>
Answer:
Heterozygous for the gene
Explanation:
Alleles are the possible alternative forms of a gene. An organism having two identical alleles of a gene is said to be homozygous for that gene. On the other hand, an organism having two dissimilar alleles for a gene is heterozygous for that gene.
For example, let's suppose that I^A and I^B are the two alleles for ABO blood type in humans. Here, an individual with one copy of I^A and one copy of I^B would be heterozygous for ABO blood type. On the other hand, genotypes I^AI^A and I^BI^B are homozygous for the ABO blood type gene.
