Question

1 in the mystical land of monsters, two creatures with different horn traits are preparing to have offspring. one monster is homozygous dominant and has a single horn (hh), while the other is homozygous recessive and has no horns (hh). use a punnett square to predict the chances of their future offspring inheriting a horn or no horn.

2 in the mysterious land of monsters, two extraordinary creatures with differing eye traits are preparing to have offspring. one creature, with two eyes, exhibits a heterozygous trait, while the other creature, with three eyes, displays a homozygous recessive trait. use a punnett square to predict the chances of their future offspring inheriting two eyes or three eyes.

Explanation:

Question 1 (Horn Trait)

Step1: Determine Parental Gametes

The homozygous dominant monster (HH) can only produce H gametes. The homozygous recessive monster (hh) can only produce h gametes.

Step2: Fill Punnett Square

	H	H
h	Hh	Hh

All four squares are Hh.

Step3: Calculate Genotype Percentages

• HH: 0/4 = 0%
• Hh: 4/4 = 100%
• hh: 0/4 = 0%

Step4: Calculate Phenotype Percentages

Since H is dominant, Hh shows the horn phenotype. So horn: 100%, no horn: 0%.

Step1: Determine Parental Genotypes and Gametes

Let two eyes be dominant (E) and three eyes be recessive (e). Heterozygous two - eye: Ee (produces E and e gametes). Homozygous recessive three - eye: ee (produces e gametes).

Step2: Fill Punnett Square

	E	e
e	Ee	ee

Step3: Calculate Genotype Percentages

• EE: 0/4 = 0%
• Ee: 2/4 = 50%
• ee: 2/4 = 50%

Step4: Calculate Phenotype Percentages

• Two eyes (E_: Ee or EE): Ee is 50%, EE is 0%, so two eyes: 50%
• Three eyes (ee): 50%

Answer:

Genotype: HH 0%, Hh 100%, hh 0%
Phenotype: Horn 100%, No horn 0%
