According to the principle of segregation, gene pairs for a trait are split during the formation of gametes.

<u>Explanation</u>:

  • This segregation was first observed by Gregor Mendel. He used pea plants for studying genetics.
  • He crossed the pea plants and he discovered that traits in the offspring are not like the parental plants.
  • He understands that alleles encoding the traits of each parental plant are separated during the formation of reproductive cells.
  • By this only Mendel observed the principle of segregation. During meiosis only segregation of gene takes place and that produces reproductive cells called gametes.

An unknown bacterium produces colorless colonies when inoculated onto an EMB plate. Predict what you would see if you inoculated
marshall27 [118]

The EMB (Eosin Methylene Blue) agar is a selective and differential agar medium. It contains sucrose and lactose as fermentable substrates together with Eosin Y and methylene blue dyes which in combination gives the agar its characteristic color when prepared and serves as a pH indicator as well as an inhibitor of growth of Gram-positive bacteria. Hence, it is primarily used to isolate Gram-negative fecal coliforms while some positive fecal coliforms such as Staphylococci are also able to grow.

These coliforms are of two types:

  • Lactose or sucrose fermenting coliforms form metallic sheens on the agar as a result of acid production and the response of the indicator to the increased acidity.
  • Non-lactose/sucrose fermenters are only able to produce acid by protein deamination. Hence they either form colorless or pinkish colonies on the agar

On the other hand, Mannitol salt agar is a selective and differential agar medium that is primarily used to isolate Staphylococcal bacteria. The presence of sodium chloride in the medium makes it a partial or complete inhibitor of other bacteria.

Hence, an unknown bacterium that forms colorless colonies on EMB will either be a non-lactose fermenting, Gram-negative coliform that will hardly grow on Mannitol salt agar, or a Gram-positive fecal Staphylococcus.

Staphylococci bacteria are of two types:

  • Coagulase-positive will form yellow colonies on the Mannitol salt agar.
  • Coagulase-negative will form red colonies on the Mannitol salt agar.

Explain the importance of biodiversity to an ecosystem. in your answer, be sure to:
MArishka [77]
Biodiversity supports biological system efficiency where every specie, regardless of how little, all have a vital part to play. For instance, A bigger number of plant species implies a more prominent assortment of products. More noteworthy species assorted variety guarantees common maintainability for all living things.
