Which of the following statements correctly describes the terms monohybrid cross and dihybrid cross? O A monohybrid cross results in a 9:3:3:1 ratio, whereas a dihybrid cross gives a 3:1 ratio O A dihybrid cross involves organisms that are heterozygous for two characters/traits, both of which exhibit incomplete dominance, and a monohybrid cross involves organisms that are heterozygous for only one character/trait with complete dominance O A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents O A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied

A wild-type fruit fly (heterozygous for gray body color andred eyes) is mated with a black fruit fly with purple eyes. Theoffspring are wild-type, 721; black purple, 751; gray purple, 49;black red, 45. What is the recombination frequency betweenthese genes for body color and eye color? Using informationfrom problem 3, what fruit flies (genotypes and phenotypes)would you mate to determine the order of the body color, wingsize, and eye color genes on the chromosome?
In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
. As we learned in this chapter, the white mutation ofDrosophila studied by Thomas Hunt Morgan isX-linked and recessive to wild type. When truebreeding white-eyed males carrying this mutationwere crossed with true-breeding purple-eyed females,all the F1 progeny had wild-type (red) eyes. When theF1 progeny were intercrossed, the F2 progeny emergedin the ratio 3/8 wild-type females: 1/4 white-eyedmales: 3/16 wild-type males: 1/8 purple-eyed females:1/16 purple-eyed males.a. Formulate a hypothesis to explain the inheritanceof these eye colors.b. Predict the F1 and F2 progeny if the parental crosswas reversed (that is, if the parental cross wasbetween true-breeding white-eyed females andtrue-breeding purple-eyed males).
A recessive allele in mice results in an unusally long neck. Sometimes, during early embryonic development, the long neck causesthe embryo to die. An experimenter began with a population oftrue-breeding normal mice and true-breeding mice with longnecks. Crosses were made between these two populations to produce an F1 generation of mice with normal necks. The F1 micewere then mated to each other to obtain an F2 generation. For themice that were born alive, the following data were obtained:522 mice with normal necks62 mice with long necksWhat percentage of homozygous mice (that would have had longnecks if they had survived) died during embryonic development?
Each box represents a potential offspring. Notice that genotypically speaking, they are all the same. Theyare all heterozygous (genotype) which means their phenotype is dark coloration. So, there is 100% chanceof producing a dark eyed, heterozygous offspring. What if that offspring mated with a light eyedindividual? Can you make a Punnett Square for that?Write the Genotypes and Phenotypes of the parents on the left of the square. Complete the square, thenwrite the potential offspring’s genotypes and phenotypes on the right of the square. Parents: Offspring:Genotypes: phenotypes:  What are the genotypes of the resulting offspring? What are the phenotypes of the resulting offspring?
In the world of Weeping angels, those with pointy wings are (A_), while those with round wings are (aa). In the efforts to explore this extraordinary species, you wish to determine the genotype of a pointy winged angel. Luckily, you have trapped a round winged angel that you can cross your pointy winged angel with. If the pointy winged angel is homozygous what phenotypic ratio do you expect from their offspring? (Pointy wing: round wing) Group of answer choices a. 1:0 b. 2:1 c. 1:1 d. 3:1

20. 20.Which among the following statements is INCORRECT? A. Codominance is evident when a cross between organisms with two different phenotypes produces offspring that exhibits both parental traits because the alleles for each trait are neither completely dominant nor recessive B. Incomplete dominance is evident when a cross between a white carnation and a red carnation results in a pink carnation flower. C. Law of dominance state that if the alleles of a specific gene differ from each other, only one phenotype will be expressed while the other is masked D. The inheritance of one trait does not affect the inheritance of the other trait especially if the allele of the other trait is located in a different chromosome
