2. Male chickens (called roosters) have a red flap of skin growing from their heads called combs. These are used o attract female chickens (called hens). The bigger combs are called single combs. Roosters with single combs are nore attractive to hens than those with smaller combs called rose combs. Saleh mates his hybrid single comb ooster named Sancho, to his favorite rose combed hen, named Maria so they can make baby chickens (chicks). reate a Punnett Square to show the possibilities that could result from this mating. Alleles and Phenotype All Genotype and Parent Genotypes Punnett Square Phenotype Possibilities Genotype Phenotype Allele Phenotype Dad Mom . Maria's Genotype . Sancho's Genotype .What is the probability of having a single comb chick? 1. What is the probability of rose comb chick? . What is the probability for a heterozygous?

This is a Hw

Which of the following scenarios shows the founder effect? O Two different species of frogs mate with each other and create a triploid hybrid. This hybrid can produce viable offspring via parthenogenesis OA small group of salamanders moves away from the large population. By chance, this newly established population contains only individuals with the same genetic mutation O Butterflies with a foul taste are left alone by predators, while those without the foul taste are eaten O An avalanche wiped out 90% of a snow hare population, by chance, only the dark brown hares survived O Cichlid fish in lake Tanganyika were under the influence of different microhabitats and evolved based on the local environmental conditions

Part 2. Do one more example of a monohybrid cross. This time assign the letter "B" for onion taste. Being sweet is dominant controlled by allele (B) and being bitter is recessive-controlled by allele (b). Cross individuals who are both heterozygous for this trait. 5. What is the genotype of each of these heterozygous individuals? 6. What is the phenotype of these heterozygous individuals? Complete the Punnett square below using the alleles you just listed. 7. What are the resulting genotypes and their ratios or %? 8. What are the resulting phenotypes and their ratios or %? Figure 3. Monohybrid Cross for Onion Taste. 103

4. Two genes control color in lentils. A- B- lentils are black, A- bb are cream, aa B- are brown, and aa bb are white. A black lentil plant was crossed to a white lentil and all F1 progeny were black. F1 lentils were crossed to each other and you observe 105 black, 27 cream, 24 brown, and 14 white. 4A. What are the genotypes of the F1 lentils? A. A mix of A-B- genotypes. В. АаBb C. Can't say Answer: 4B. Rounding down any expected progeny to the nearest whole number, what is the Chi squared statistic (rounded to tenths place) for whether your observed progeny fit your expectation for unlinked genes? Answer: 4C. What is the statistical significance of this value? (use the contingency table in the book). Answer:

5. Flower color is determined by the pathway below. You a crossing a true-breeding white-flowered plant thatcannot produce gene A and a true-breeding white-flowered plant that cannot produce gene B.Gene A Gene BWhite  White  Purplea. What are the genotypes of the P-generation?b. What are the genotypes and phenotypes of the F1 generation?c. What are the genotypes and phenotypes of the F2 generation? What is the phenotypic ratio?(Purple:White)

1. Alleles of the gene that determines seed coat patternsin lentils can be organized in a dominance series:marbled > spotted = dotted (codominant alleles) >clear. A lentil plant homozygous for the marbled seedcoat pattern allele was crossed to one homozygous forthe spotted pattern allele. In another cross, a homozygous dotted lentil plant was crossed to one homozygous for clear. An F1 plant from the first cross wasthen mated to an F1 plant from the second cross.a. What phenotypes in what proportions are expectedfrom this mating between the two F1 types?b. What are the expected phenotypes of the F1 plantsfrom the two original parental crosses?

2. A red snapdragon is crossed with a white snapdragon plant. Red pigment is incompletely dominant and white has no pigments and is recessive. Please draw the genetic chart to show the genotypes and phenotypes of P, Fl and F2 if F1 plants crossbred with each other. are

1. Human males are more likely to be color blind than females. This is because of mutations to genes located on the X-chromosome, this is a result of these genes ___ a. being sex-linked traits and not hidden by a different allele from the other parent  b. giving females more cones and rods which allows for more vision of the color spectrum.  c. all answers are true  d. not being sorted independently

How do I graph this problem on a punnet square?
