Question
7. Assume that one of Squidward's sons, who is heterozygous for the light blue body color, married a girl that was also heterozygous.

Answer
7.A. The possible genotypes are TT, Tt, and tt. The possible phenotypes are light blue skin and light green skin.B. Chance of a child with light blue skin is 75%.C. Chance of a child with light green skin is 25%.8.A. Genotype possibilities are TT and Tt, and all their children will be "tall-eyed."B. Yes, the hospital made a mistake. Since both parents share a dominant allele (T) for tall eyeballs, it's impossible for them to produce a child with short eyeballs represented by tt, as neither parent provides the 'minor trait' allele 't'. If baby Lil' Krabby has short eyeballs (tt genotype), this implies an apparent question about its parentage.
Explanation
## Step 1### **Genotype and Phenotype**The concept of genotype and phenotype is fundamental in understanding Mendelian genetics. The genotype refers to the genetic makeup of an organism, while the phenotype is the observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.## Step 2### **Punnett Square**A Punnett square is a graphical representation used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The square is a visual representation of Mendelian inheritance.## Step 3### **Mendelian Genetics**Mendelian genetics is the study of how traits are passed from parents to offspring. Gregor Mendel's laws of inheritance state that traits are passed from parents to offspring through genes, which are made up of DNA.## Step 4### **Heterozygous and Homozygous**Heterozygous means having two different alleles of a particular gene. Homozygous means having two identical alleles of a particular gene.## Step 5### **Dominant and Recessive Traits**Dominant traits are those that are expressed when only one copy of the dominant allele is present. Recessive traits are those that are only expressed when two copies of the recessive allele are present.## Step 6### **Probability Calculation**The probability of an event is calculated by dividing the number of ways the event can occur by the total number of outcomes.
