-
Hybrid : different
-
Homozygous : Same
-
Heteroygous : different
-
Diplogous : mixed
Correct Answer
A. Homozygous : SameExplanation
The correct answer is "Homozygous: Same". Homozygous refers to having two identical alleles for a specific trait. In this context, SpongeBob and Squidward are bragging about being "purebred," which means they have two identical alleles for the selected trait they are discussing. This is why the term "Homozygous" fits as the correct answer.Rate this question:

-
(red)
-
(pink)
-
(green)
-
(white)
Correct Answer
A. (pink)Explanation
When a homozygous red shell snail (rr) is crossed with a homozygous white shell snail (ww), the resulting offspring will have the genotype of (rw), which represents a pink shell. This is because the gene for red shell (r) is incompletely dominant over the gene for white shell (w), resulting in a blend of the two colors. Therefore, the children of this cross would have a pink shell phenotype.Rate this question:

SpongeBob's aunt and uncle, SpongeWilma and SpongeWilbur, have the [RR] biggest round eyes in the family. Wilma is believed to be heterozygous for her [Rr] round eye shape, while Wilbur's family brags that they have pure line. You may have already completed a punnett square to show the possibilities that would result if SpongeWilbur and SpongeWilma would have children. What genotype would NOT be found in their children?
-
[RR]
-
[Rr]
-
[rr]
Correct Answer
A. [rr]Explanation
The genotype [rr] would not be found in their children because both SpongeWilma and SpongeWilbur have at least one dominant allele for round eyes ([Rr] and [RR] respectively). In order for a child to have the genotype [rr], they would need to inherit a recessive allele from both parents, which is not possible in this case.Rate this question:

Sherry, who is a pink-shelled snail, would like to have kids with red shells. What genotype would her husband snaill must be to marry for the best chance for kids with red shells?
-
[rr]results in 50% red-shell children
-
[rw] results in 25% red-shell children
-
[ww]
Correct Answer
A. [rr]results in 50% red-shell childrenExplanation
If Sherry, who has a genotype of [rr], wants to have kids with red shells, her husband snail must also have a genotype of [rr]. This is because the genotype [rr] is homozygous for the red shell trait. When both parents have the same genotype for the desired trait, there is a higher chance of passing on that trait to their children. In this case, having a genotype of [rr] for both parents would result in a 50% chance of having children with red shells.Rate this question:

SpongeBob and his pal Patrick enjoy jellyfishing at Jellyfish Fields! The jellyfish are known as Goobers. Many of the jellyfish are yellow (yy) and blue (bb), but some end up green as a result of incomplete dominance. What would happen if SpongeBob and Patrick crossed a blue jellyfish with a goober? What colors would result from this cross?
-
Yellow and Blue
-
Yellow and Green
-
Green and Blue
-
All yellow
-
All blue
Correct Answer
A. Green and BlueExplanation
If SpongeBob and Patrick crossed a blue jellyfish with a goober, the resulting colors would be green and blue. This is because some jellyfish end up green as a result of incomplete dominance, meaning that the traits of both parents are expressed in the offspring. In this case, the blue jellyfish would contribute the blue color trait, while the goober would contribute the yellow color trait. When these traits combine, the offspring would have both green and blue colors.Rate this question:

-
[rr]
-
[rb]
-
[bb]
-
[Rb]
Correct Answer
A. [rb]Explanation
When SpongeBob crosses a Poofkin with a red flower (rr) with a Poofkin with blue flowers (bb), the offspring will have a genotype of [rb]. This is because the red gene (r) is incompletely dominant over the blue gene (b), resulting in a blend of the two colors. Therefore, the phenotype of the offspring will be a blend of red and blue, which is represented by [rb].Rate this question:

Correct Answer
A. 500Explanation
If SpongeBob crossed two Poofkins with purple flowers, the resulting cross would yield 500 offspring with purple flowers. This is because the question states that Poofkins have incomplete dominance, meaning that when two different alleles (in this case, red and blue) are present, they blend together to create a third phenotype (purple). Therefore, when two Poofkins with purple flowers are crossed, their offspring will also have purple flowers. Since the question states that there were 1,000 seeds in total, and all of them will be purple, the number of purple offspring will be 500.Rate this question:

Correct Answer
A. 25%Explanation
If SpongeBob and Patrick crossed two heterozygous green "goobers," the offspring would have a 25% chance of being yellow. This is because green color in the jellyfish is a result of incomplete dominance, where neither the yellow nor blue allele is completely dominant over the other. When two heterozygous green "goobers" are crossed, the possible genotypes of the offspring are YY (yellow), Yb (green), and bb (blue). Therefore, only 25% of the offspring would have the genotype for yellow color.Rate this question:

In incomplete dominance, when two different alleles are crossed, the resulting offspring will exhibit a phenotype that is intermediate between the two parental phenotypes. In this case, crossing a poofkin with red flowers (rr) with a poofkin with blue flowers (bb) would result in offspring with the genotype rb. Since rb represents a purple flower, all of the offspring would have purple flowers. Therefore, the correct answer is 100%.Rate this question:
