Tools Background Layout - Theme Transition Punnett Square WorkSheet Complete the following dihybrid cross: Fill in the Punnett squares, list the genotypic ratio and the phenotypic ratio that describe the offspring. Be sure to keep the letters the same and remember that the capital letter is dominant. Remember: For the genotypic ratio - it's HD:Ht:HR. For the F1 phenotypic ratio - It's Dom:Rec. For the F2 phenotypic ratio - It's DomDom:DomRec: RecDom:RecRec. P generation - Two true-breeding (homozygous) Portuguese Water Dogs.

Practice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.

NAME: Patterns of Inheritance Worksheet 1. True Breeding Parental Cross A homozygous dominant purple flowered plant is crossed with a homozygous recessive white flowered plant. a. What are the genotypes of the parent plants? (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square. (P=Purple, p=white) b. What is the genotype of all F₁ plants? 1 b. c. What is the phenotype of all F₁ plants? C. d. How many plants out of 4 will produce white flowers? d. a. 2. Monohybrid Cross: The F₁ offspring from the above problem are allowed to self fertilize. a. What are the genotypes of the F₁ parents? a. (Use the Punnett square to determine the outcomes of this cross. Remember to place the gametes along the left side and top of the square.) b. What is the genotype ratio for this cross? c. What is the phenotype ratio for this cross? d. How many plants out of 4 will produces white flowers? d. b. C.
