Answer is Homologous.

A diploid individual having two different alleles for a specific trait is called heterozygous. An allele is the alternative form of the same gene. The cells in diploid organisms contain sets of homologous chromosomes, which are paired chromosomes. Each chromosome of a homologous pair has the same genes on the same positions. Although homologous chromosomes have the same genes, they may have different alleles for those genes.  

Example: The gene for seed color trait in a pea plant exists in pair. One gene or allele for yellow seed (R) and the other for green seed color (r). A heterozygous plant would contain alleles for seed color (Rr). Gene R is present one chromosome and its allele (r) is present on the other chromosome of the homologous pair.

Consider this microscopic image of bacteria. mc005-1.jpg Which bacterial shape is shown in the image?
e-lub [12.9K]

The right answer is spiral.

Size and shape vary from one bacterium to another. The majority of bacteria have a size between 0.5-5 μm in diameter.

Most bacteria are either spherical or rod-shaped. In the first case they are called cocci (of the Greek kókkos, grain) and in the second bacilli (of Latin baculus, rod). There are also intermediate forms: coccobacilli. Some rod-shaped bacteria are slightly curved like vibrio. Other bacteria are helicoidal. They are spiral if the form is invariable and rigid, spirochaetes if the body is flexible and can change shape.
