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.
<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
Im pretty sure its
A. Number of Organisms
B. Amount of Matter
A million sorrys if im wrong :(
Answer:
Blood cells are produced in the bone marrow of the body more specifically they become blood cells from first being stem cells which then divide until they reach a mature red blood cell stage. ( or other types of cells, stem cells are like the blank template for either red blood cells, white blood cells, or platelettes.)

D: It is based on facts.
Explanation:
The reason is because science is based off of data and analsys which
