Answer/Explanation:

Blue eyes have less melanin than brown eyes. Melanin helps vision and hearing. It also affects behaviors and balance.

This means Brown eyes are healthier than blue eyes.

Studies have shown even for cats that if they have white fur and blue eyes(lack of melanin) that they would have a 90% chance of being born deaf.

Hypothesis: If the type of the food available changes, then the frequency of beak types will change, because birds with beaks mo

dangina [55]

The correct answer is: If generation 3 had flock distributions similar to those shown in the graph below.

After the change in food, the beak phenotype changes in order to adapt. So, if fruit is removed, the phenotype of birds’ beaks should change according to the change in environment. The graph below shows that there is no change, so it wouldn’t support the hypothesis that food changes beak types.

1. a) father (Rr), mother (rr)

b) from the attached file(1)

c) the possible genotypes are

Rr - 50%
rr - 50%

d) but from the information given above the only possible genotype for SpongeGerdy is Rr, because we were told that she was squarepants

e) Rr

f) from the attached file(2)

g) the possible genotypes are

RR - 25%
Rr - 50%
rr - 25%

h) the genotypes for squarepants are RR and Rr

therefore probability is (25 + 50)% = 75% or 3/4

i) the only genotype for roundpants is rr

therefore probability is 25% or 1/4

2. a) wilba - Ee , wilbur -EE

b) from the attached file(3)

c) the possible genotypes are

EE - 50%
Ee - 50%

d) the genotypes for round eye are EE and Ee

therefore probability is (50 + 50)% = 100% or 1

e) the only genotype for oval eye is ee

therefore probability is 0

3. a) squidward - BB . squidette - bb

b) from the attached file(4)

c) the only possible gene is Bb - 100% or 1

d) the genotypes for a light blue skin are BB and Bb

therefore probability is (0 + 100)% = 100% or 1

e) the only genotype for a light green skin is bb

therefore probability is 0

f) No, they are not. this is because they are heterozygous i.e.( they carry gene for a light green skin)

g) from the attached file(5)

h) the possible genotypes are

BB - 25%
Bb - 50%
bb - 25%

i) the genotypes for a light blue skin are BB and Bb

therefore probability is (25 + 50)% = 75% or 3/4

j) the only genotype for a light green skin is bb

therefore probability is 25% or 1/4
