  • Unicellular organisms are further divided into Prokaryotic and Eukaryotic organisms
  • Examples of prokaryotic organisms are bacteria and Eukaryotic are protozoa and unicellular algae, however many eukaryotes are multi cellular as well.
  • These organisms have to carry out life sustaining metabolic processes for their survival.
  • These processes are metabolism, homeostasis and reproduction. Metabolism is important as it involves conversion of food into energy for cellular processes. Homeostasis for maintaining a constant internal physical and chemical conditions and reproduction is by cell division.
  • Multi cellular organisms as the name says unlike unicellular organisms consists of more than one cells.

In flies, red eyes (R) are dominant to brown eyes (r). A heterozygous fly is crossed with a homozygous recessive fly
hichkok12 [17]

Answer:

The cross of a heterozygous fly with a homozygous fly can be shown as follows:

         r            r

R      Rr           Rr

r        rr            rr

The results show that there is a 50% probability that the flies produced will have red eyes. Their genotypes will be heterozygous.

The results of the punnet square show that there will be a 50% probability that the offsprings will have brown eyes. Their genotype will be homozygous recessive.

A homozygous trait can be described as a trait which has same alleles for the gene which encodes the trait. Heterozygous means that both the alleles for the trait will be different.
