Assume that a gene controls the expression of a trait in which affected children occur only in families where one or both parents are also affected; children who are normal may have parents who are (1) both normal, (2) one normal and one affected, or (3) both affected. A normal woman marries an affected man, one of whose parents was normal. What is the F1 phenotypic ratio of this cross?

In the common daisy, genes A and B control flower color. Both genes have a dominant allele (A or B) and a recessive allele (a or b). At least one copy of each dominant allele is required for flowers to be colorful instead of white. (Explain and Justify your answers) 21.1) Predict the genotypes and phenotypes of the F1 progeny of a cross between two white-flowered plants, one homozygous AA and the other homozygous BB. A) AA bb, white B) aa BB, white C) Aa Bb, colorful D) Aa Bb, white E) aa bb, colorful 21.2) Predict the phenotypic ratio of the F2 progeny of a cross between two white-flowered plants, one homozygous AA and the other homozygous BB. A) 3 colorful : 1 white B) 9 colorful : 7 white C) 9 white : 7 colorful D) 15 white : 1 colorful E) 15 colorful : 1 white 21.3) The inheritance pattern of daisy flower color provides an example of what type of gene interaction? A) additivity…
In a cross involving polygenic inheritance, three (3) gene pairs control plant height. The shortest andtallest plants are 12 cm and 24 cm, respectively. What height should all F1s display if the shortest andtallest plants were crossed, assuming environmental factors are the same?
What is a reciprocal cross? Suppose that a gene is found as a wildtype (functional) allele and a recessive mutant (nonfunctional)allele. What would be the expected outcomes of reciprocal crossesif a true-breeding normal individual was crossed to a true-breedingindividual carrying the mutant allele? What would be the results ifthe gene is maternally inherited?
In goats, development of the beard is due to a recessive gene. The following cross involving true-breeding goats was made and car- ried to the F2 generation: P;: bearded female x beardless male F1: all bearded males and beardless females ´1/8 beardless males | 3/8 bearded males 3/8 beardless females 1/8 bearded females F; × F, Offer an explanation for the inheritance and expression of this trait, diagramming the cross. Propose one or more crosses to test your hypothesis.
In guinea pigs, rough coat (R) is dominant to smooth coat (r). If a homozygous rough-coated animal is crossed with a smooth-coated one: What will be the phenotype(s) of the F1 generation? What will be the phenotype(s) of the F2 generation? What will be the phenotype(s) of the offspring resulting from a cross of an F1 individual back to its rough parent? What will be the phenotype(s) of the offspring of a cross of an F1 individual back to its smooth parent?
Pigment in mouse fur is only produced when the C allele is present. Individuals of the cc genotype are white. If color is present, it may be determined by the A, a alleles. AA or Aa results in agouti color, while aa results in black coats. (a) What F1 and F2 genotypic and phenotypic ratios are obtained from a cross between AACC and aacc mice? (b) In three crosses between agouti females whose genotypes were unknown and males of the aacc genotype, the following phenotypic ratios were obtained: (1) 8 agouti (2) 9 agouti (3) 4 agouti 8 white 10 black 5 black 10 white What are the genotypes of these female parents?
A geneticist crosses two yellow mice with straight hair and obtains the following progeny: 12 yellow, straight 16 yellow, fuzzy 14 gray, straight 112 gray, fuzzya. Provide a genetic explanation for the results and assign genotypes to theparents and progeny of this cross.b. What additional crosses might be carried out to determine if yourexplanation is correct?
Hemophilia is caused by an X-linked recessive mutation in humans. If a man whose paternal uncle (father's brother) was a hemophiliac marries a woman whose brother is also a hemophiliac, what is the probability that their first child will have hemophilia?

A snapdragon plant with violet flowers was crossed with another such plant with white flowers. The F1 progeny obtained had pink flowers. Explain, in brief, the inheritance pattern seen in offsprings of F1 generation?
Pigment in the mouse is produced only when the C allele is present.Individuals of the cc genotype have no color. If color is present,it may be determined by the A and a alleles.

A mutant sex-linked trait called “notched” (N) is deadly in Drosophila when homozygous in females. Males who have a single N allele will also die. The heterozygous condition (Nn) causes small notches on the wing. The normal condition in both male and females is represented by the allele n. a) Indicate the phenotypes of the F1 generation from the following cross: XNXn x XnY b) Explain why dead females are never found in the F1 generation no matter which parents are crossed. c) Explain why the mating of female XNXn and a male XNy is unlikely.
You have set up a fly cross between red-eyed male flies and white-eyed female flies. Several days later, you look at the F1 progeny to examine the eye phenotypes. You notice that all of the F1 males have white eyes and all of the F1 females have red eyes. These observations tell you that the gene for red eye color is most likely:
