Answer:
a) 
b)
c)
d) 
Explanation:
The correct question is
Organisms with the genotypes AABbCcDd and AaBbCcDd are crossed. What are the expected proportions of the following progeny?
a. A_B_C_D_
b. AabbCcDd
c. a phenotype identical to either parent
d. A_B_ccdd
Solution
In such question the probability for each allele pair is to be determines separately
For instance,
AA * Aa will produce AA, Aa, AA, Aa this means that all the the probability of getting both AA and Aa is 
Like wise when Bb and Bb are crossed, BB, Bb, Bb, and bb are produced. So the probability of getting dominant trait i.e BB or Bb is 
and recessive trait i.e bb is 
Chance to get homozygous bb only or BB only is
and chance of getting Bb is
Like Bb and Bb cross, the same will be the probabilities for Cc and Cc cross and Dd and Dd cross

Answer:
The first thing I did not see you at least two of us play in part of the reason I have a feeling it was not the few ia
No she needs to collect more data like for example have them run 60 meters and then 90 meters then take the average of the dog and cats time
Answer:
calories and Calories are the same thing, and if someone eats 2000 calories then they have eaten 2000 calories
Explanation:
Answer:
a. blue and featherless
Explanation:
- Feathers (F) are dominant to no feathers (f)
- Blue body (B) is dominant to white body (b)
If we testcross a dihybrid, we are crossing a homozygous recessive individual with a heterozygous individual.
Recombination is a rare event in meiosis, so the more abundant offspring are always the parentals, and the less abundant offspring are the recombinant ones.
In this case, bf/bf and BF/bf are the parentals and Bf/bf and bF/bf are the recombinants.
The option a. Blue and featherless (Bf/bf) offspring are the recombinant babies.
