7 0

Anaphylaxis, also called allergic or anaphylactic shock, is a sudden, severe and life-threatening allergic reaction that involves the whole body. The reaction is marked by constriction of the airways, leading to difficulty breathing.

Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. An allergen is a substance that can cause an allergic reaction.

Anaphylactic shock is a rare but severe allergic reaction that can be deadly if you don't treat it right away. It's most often caused by an allergy to food, insect bites, or certain medications. A shot of a drug called epinephrine is needed immediately.

How many different offspring genotypes are expected in a trihybrid cross between parents heterozygous for all three traits when

aalyn [17]

Answer:

27 genotypes and 8 phenotypes

Explanation:

Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:

I add an image where you can see all the 27 genotypes and frequencies.

Finally, all the 8 phenotypes with the following frequencies:

27/64 A-B-D-

9/64 A-B-dd

9/64 A-bbD-

9/64 aaB-D-

3/64 A-bbdd

3/64 aaB-dd

3/64 aabbD-

<u>1/64 aabbdd </u>

Total 64/64

Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)
