If a gray fly is crossed with a heterozygous black fly, which combination below represents the parental cross?

Answers

Answer:

hello your question lacks the required options hence I will give you a  general answer

answer :  gg ( gray fly )  * Gg ( heterozygous black fly )

Explanation:

Let black body ( G ) be the dominant allele to gray body ( g )

hence the possible combination that will represent a parental cross when a gray fly is crossed with a heterozygous Black fly will be

gg ( gray fly )  * Gg ( heterozygous black fly )

What is five kingdom classification?

The main purpose of the classification of the Five kingdom has been known R.H. Whittaker.  The five kindoms that has were included in this proposal were the Fungi, Protista, Monera.

Animalia as well as the kingdom Plantae. There are mainly five criteria or the conditions based on which the classification has been madeup of. These criteria has been includes the structure of the cell,  as well as the nutrition mode, organisation of the thallus, or the relations of reproduction and phylogenetic.

Based on shoe characteristics they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things.

Therefore, Planting of trees is not a factor contributing to the loss of biodiversity. Thus, option C is correct.
