**Genetics: Understanding Seed Traits through Punnett Squares**The purpose of this exercise is to explore genetic crosses involving seed traits. The trait being studied is round seeds (dominant) and wrinkled seeds (recessive).### Exercise Instructions:For each cross listed below, set up a Punnett square to determine the distribution of offspring traits. A Punnett square is a grid that helps visualize the combinations of parental alleles and predict the genetic variability in the offspring.#### Cross 1: \(Rr \times rr\)Haploid Gametes:- Parent 1 (Rr) produces two types of gametes: R and r.- Parent 2 (rr) produces one type of gamete: r.Fill in the Punnett square to show possible offspring combinations.#### Graph/Diagram 1:| | r | r ||-------|---------|---------|| **R** | Rr | Rr || **r** | rr | rr |a. **What percentage of the offspring will be round?** __________#### Cross 2: \(Rr \times Rr\)Haploid Gametes:- Both parents produce two types of gametes: R and r.Fill in the Punnett square to show possible offspring combinations.#### Graph/Diagram 2:| | R | r ||-------|---------|---------|| **R** | RR | Rr || **r** | Rr | rr |b. **What percentage of the offspring will be round?** __________#### Cross 3: \(RR \times Rr\)Haploid Gametes:- Parent 1 (RR) produces one type of gamete: R.- Parent 2 (Rr) produces two types of gametes: R and r.Fill in the Punnett square to show possible offspring combinations.#### Graph/Diagram 3:| | R | r ||-------|---------|---------|| **R** | RR | Rr || **R** | RR | Rr |c. **What percentage of the offspring will be round?** __________### Notes:- **Round seeds** represent the dominant trait (R).- **Wrinkled seeds** ### Genetics Worksheet: Understanding Genotypes and Phenotypes#### Section 1: Identifying Heterozygous (HE) and Homozygous (HO) GenotypesFor each genotype, indicate whether it is heterozygous (HE) or homozygous (HO):- **AA** ____________________- **Bb** ____________________- **Cc** ____________________- **Dd** ____________________- **Ee** ____________________- **ff** ____________________- **GG** ____________________- **HH** ____________________- **Ii** ____________________- **Jj** ____________________- **kk** ____________________- **Ll** ____________________- **Mm** ____________________- **nn** ____________________- **OO** ____________________- **Pp** ____________________#### Section 2: Determining Phenotypes from GenotypesFor each of the genotypes below, determine the phenotype.- **Purple flowers are dominant to white flowers** - **PP** ____________________ - **Pp** ____________________ - **pp** ____________________- **Brown eyes are dominant to blue eyes** - **BB** ____________________ - **Bb** ____________________ - **bb** ____________________- **Round seeds are dominant to wrinkled** - **RR** ____________________ - **Rr** ____________________ - **rr** ____________________- **Bobtails are recessive (long tails dominant)** - **TT** ____________________ - **Tt** ____________________ - **tt** ____________________#### Section 3: Listing Genotypes Based on PhenotypesFor each phenotype, list the possible genotypes. Remember to use the letter of the dominant trait.- **Straight hair is dominant to curly** - **_________ straight** - **_________ straight** - **_________ curly**- **Pointed heads are dominant to round heads** - **_________ pointed** - **_________ pointed** - **_________ round**This worksheet helps students understand the basics of genetics, focusing on identifying and differentiating between heterozygous and homozygous genotypes, as well as determining phenotypes from given genotypes. Additionally, it guides students in listing possible genotypes for given phenotypes based on dominant and recessive traits.
