A human with heterozygous genotype can have a dominant phenotype if one of the alleles complete mask the effects of the other.
- Heterozygous genotype involves two different alleles, unlike homzygous genotypes in which the alleles are the same.
- When the two alleles of an heterozygous genotype exert equal effects on one another, they are said to be codominant.
- When one of the alleles of an heterozygous genotype incompletely exert its effects on the other allele, it is said to be incomplete dominance.
- When one of the alleles complete dominates and masks the effects of the other allele, it is said to be dominant.
Hence, a dominant allele will always produce a dominant phenotype even if the genotype of the organism is heterozygous.

1. Exchange materials with its environment efficently
Some scientists are studying a newly discovered microbe and determine that it consists of a single cell, lacking a nucleus. this organism could be <u>a bacterium.</u>
<u></u>
<h3>What do you mean by bacterium?</h3>
- Any of a large group of one-celled organisms that reproduce by fission or by generating spores, lack a cell nucleus, and occasionally cause disease.
- They are the most prevalent life forms on Earth, present in all living organisms as well as all climatic conditions.
<h3>What can be discovered in bacteria?</h3>
- Its gel-like matrix, which also contains other cell components like ribosomes, chromosomes, and plasmids, is made up of water, enzymes, nutrients, waste products, and gases.
- The cytoplasm and all of its elements are enclosed by the cell membrane.
- Bacteria do not have a nucleus that is contained in a membrane like eukaryotic (true) cells do.

There are no various sorts of bacterial provinces in Anna's example. Just Serratia marcescens was discovered in light of the fact that the microorganisms in the specimen all had a similar shape and size. Microbiologists need to detach bacterial provinces from an example to have the capacity to take a gander at what sorts of microscopic organisms are in the example.
