In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, mesh-like membrane called peptidoglycan. Bacteria with thick peptidoglycan are called gram positive. If the peptidoglycan layer is thin, it's classified as gram negative.

Explanation:

The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.

For the characteristic "seed color" the green color would be G and yellow represented as g.

At the cross of two heterozygous squashs:

- <u>Punnett's Square</u>:

Alleles    G         g

G           GG       Gg

g           Gg        gg

Offspring:

  • A pumpkin of green seeds GG (25%)
  • Two pumpkins of green heterozygous seeds Gg (50%)
  • One pumpkin of yellow seeds gg (25%)

Genotype proportion 1:2:1

Phenotype proportion 3:1
