Answer:

This statement refers to Test Cross.

Explanation:

Generally a Test cross involving an individual with a homozygous recessive trait . When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (either homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous for a trait, then approximately half of the offspring will display the recessive phenotype. If all the offspring carry dominant phenotype, Then the unknown genotype is homozygous.

The characteristics that distinguish each of the five kingdoms can range from the number of cells and their structure to the way the organism moves.

The five kingdoms of classification are as follows:

  1. Protist
  2. Animalia
  3. Monera
  4. Plantae
  5. Fungi

Protists are known to be single-celled organisms. They often have specialized appendages for movements, such as cilia or flagella, and lack the presence of a cell wall. Protists do in fact have some organelle and can be capable of photosynthesis.

Animalia refers to the animal kingdom. They are multicellular, can move through muscular systems, and get their nutrients through ingesting food. They do not have chloroplasts or cell walls.

Monera is the smallest of the 5 kingdoms, they are single-celled organisms, often lack any organelle, and may not have the ability to move.

Fungi can be of various sizes, do in fact possess cell walls, but have no chloroplast for photosynthesis. Instead, they use absorption to feed. Fungi lack the ability to move.

Finally, the Plantae kingdom is as the name suggests, the kingdom that includes all plants. These are multicellular, cannot move and get their nutrients through the use of photosynthesis.

In a cross between two strains that are true breeding for purple and white flowers, the F2 phenotypic ration would be 1/4 purple

Explanation:

Using a Punnet square, only if one individual has incomplete dominance could have this ration.   Otherwise, if the 2 individuals had a homozygous phenotype, whit one individual for dominant and the other for recessive, the ratio would be all purple.
