Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not l
andrew11 [14]

Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.

Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).

Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.

Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.

He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.

svet-max [94.6K]
<h2>Phylum Anthophyta</h2>

Explanation:

Phylum Anthophyta is the phylum of flowering plants.

Bryophytes are group of seedless non-vascular plant.They are called the amphibians of plant kingdom because to complete their life cycle, they need both water and  land.

Anthophyta are dominant group than the bryophyta because:

  • They have a well developed vascular system.
  • They have their seeds enclosed within fruits and protective sed coat that keep them viable for a long time.

what would you if cell membrane became impermeable instead of selectively permeable could cell remain alive
natali 33 [55]
If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.
