The gene D controls wing shape in flies and has two alleles: D is wild-type and dominant, and d is recessive and causes flies to
borishaifa [10]

Answer:

10% of progeny would have wild type phenotype

Explanation:

True breeding fly with wild type wings and small eyes: De/De

True breeding fly with downward wings and wild type eyes: dE/dE

Cross between them :  De/De X dE/dE = De/dE ( F1 )

Recombination frequency = 20%

Next cross, De/dE X de/de =

De/de = parental = 40%

dE/de = parental = 40%

DE/de = recombinant = 10%

de/de = recombinant = 10%

The third genotype i.e. one of the recombinant genotypes will have the wild type makeup ( DE/de ) hence 10% of flies would have wild type phenotype.

PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!
