Question

1. everyone in squidwards family has light blue skin, which is the dominant trait for body color in the hometown of squid valley. his family brags that they are a purebred line. he recently married a nice girl who has light green skin, which is a recessive trait. create a punnett - square to show the possibilities that would result if squidward and his new bride had children. use b to represent the dominant gene and b to represent the recessive gene.

a. list the possible genotypes and phenotypes for their children.
b. what are the chances of a child with light blue skin?
c. what are the chances of a child with light green skin?
d. would squidwards children all be considered purebreds? explain.

1. assume that one of squidwards sons, who is heterozygous for the light blue body color, married a girl that was also heterozygous. create a punnett - square to show the possibilities that would result if they had children.

a. list the possible genotypes and phenotypes for their children.
b. what are the chances of a child with light blue skin?
c. what are the chances of a child with light green skin?

1. mr. krabs and his wife recently had a lil krabby, but it has not been a happy occasion for them. mrs. krabs has been upset since she first saw her new baby who had short eyeballs. she claims that the hospital mixed up her baby with someone elses baby. mr. krabs is homozygous for his tall eyeballs, while his wife is heterozygous for her tall eyeballs. some members of her family have short eyes, which is the recessive trait. create a punnett - square using t for the dominant gene and t for the recessive one.

a. list the possible genotypes and phenotypes for their children.
b. did the hospital make a mistake? explain your answer.

Explanation:

Step1: Determine Squishward's family - related genotypes

Since everyone in Squishward's family has light blue skin (dominant), Squishward is likely homozygous dominant (BB). His new bride has light green skin (recessive), so her genotype is bb.

Step2: Create Punnett - square

	B	B
b	Bb	Bb

Step3: Analyze genotypes and phenotypes

A. Genotypes: All Bb. Phenotypes: All light blue - skinned.
B. Chances of light blue skin: 100% since all offspring are Bb.
C. Chances of light green skin: 0% since no offspring have the bb genotype.
D. No, they won't all be purebred. All offspring are Bb (heterozygous).

For Squishward's son (heterozygous Bb) and his wife (assume light green - skinned bb):

Step4: Create Punnett - square

	B	b
b	Bb	bb

Step5: Analyze genotypes and phenotypes

A. Genotypes: Bb, bb. Phenotypes: Light blue - skinned (Bb), light green - skinned (bb).
B. Chances of light blue skin: 50% (2 out of 4 Bb).
C. Chances of light green skin: 50% (2 out of 4 bb).

For Mr. Krabs (homozygous dominant for tall eyeballs, TT) and his wife (heterozygous Tt):

Step6: Create Punnett - square

	T	T
t	Tt	Tt

Step7: Analyze genotypes and phenotypes

A. Genotypes: TT, Tt. Phenotypes: Tall - eyeballed.
B. The hospital likely didn't make a mistake. Since Mr. Krabs is TT and his wife is Tt, all offspring will have tall eyeballs (either TT or Tt), which is consistent with the baby having tall eyeballs.

Answer:

For Squishward and his new bride:
A. Genotypes: Bb; Phenotypes: Light blue - skinned
B. 100%
C. 0%
D. No, all offspring are Bb (heterozygous)

For Squishward's son and his wife:
A. Genotypes: Bb, bb; Phenotypes: Light blue - skinned, light green - skinned
B. 50%
C. 50%

For Mr. Krabs and his wife:
A. Genotypes: TT, Tt; Phenotypes: Tall - eyeballed
B. The hospital likely didn't make a mistake.
