2. A white eyed female fly (w is a recessive allele of a gene for eye pigmentation on the X chromosome) is crossed with a red eyed male fly. a. Give the genotypes for the parental generation. b. Give the phenotypes and genotypes, and their proportions, for the F1 generation. c.Fls are crossed to one another. Give the phenotypes and genotypes, and their proportions, for the F2 generation.

Whip-poor-wills. (Camprimulgus vociferus! The population has found in two adult phenotypes: rufous(red) and gray. An ornithologist investigates the genetics of this color variation and discovers that rufous individuals are one of two genotypes (RR or Rr), while gray individuals are rr. The frequency of these genotypes at Generation 1 in northern New Jersey are: 60% RR, 20%Rr, and 20% rr. What will the phenotype frequency be in the next generation (Generation+1)?

A cross is performed between a bird with blue feathers and a bird with yellow feather. all offspring have green feathers. 2 of the birds with green feathers are crossed and the resulting generation consists of 10 blue birds, 20 green, and 9 yellow birds.What is the simplest explanation for the inheritance and what is the genotypes and phenotypes of the birds

pedigree?
For genotype assignment assume that the affected male in the
first generation is heterozygous. Assign genotypes to all other
individuals in the Pedegree

Assume hair color in yaks has incomplete dominance. Individuals with a BB genotype have black hair and individuals with a bb genotype have white hair. Which of the following crosses will result in the same number of genotypes and phenotypes in the F1 generation? Group of answer choices a Both of these crosses will result in the same number of genotypes and phenotypes in the F1 generation b Neither of these crosses will result in the same number of genotypes...

Review This pedigree shows the inheritance pattern of a recessive maternal effect gene in Drosophila. In maternal effect, the offspring's phenotype is under the control of nuclear gene products present in the mother's egg. In this example, the presence of the at allele in the mother is required for proper wing development in the offspring. Submit Previous Answers Correct In the pedigree, individuals who are wingless are indicated by a shaded symbol. The phenotypes and genotypes are only provided for...

Experiment 1: Punnett Square Crosses Set up and complete Punnett squares for these crosses (remember Y = yellow, y = blue): YY and Yy YY and yy Answer these questions: What are the resulting phenotypes? All yellow Are there any blue kernels? No How can you tell whether or not there are blue kernels? This is because Yellow allele dominates and also it still shows up over the blue allele in the heterozygous chromosomes Set up and complete a Punnett...

1. In Drosophilia, females are XX, while males are XY. Yellow bodies are determined by an X-linked recessive mutation Xb, while the dominant wild-type allele XB produces brown bodies. A heterozygous female is crossed with a brown bodied male to produce the F1 generation. a) Among the F1 generation, what genotypes and phenotypes would be expected among the progeny, and in what proportion? b) from the F1 generation, males and females are mated at random. What genotypes and phenotypes would...

In this inquiry, you will investigate a variation of the assumption that there are only two alleles per gene. In this exercise, you will cross a purebred horizontally-striped fly with a pure bred vertically-striped fly. F1 results are: F1 Observed Results: 1000 black F1 flies Question #1: Describe the genotypes of the parents? Question #2: Describe the genotype of the F1 offspring. Question #3: What pattern of inheritance seems to be operating here? Now you will cross 2 flies, one...

Select from the terms below to answer the question below Each term is used once. A) Codominance B) Incomplete Dominance C) Complete Dominance D) Pleiotropy E) Genetic Heterogeneity F) Epistasis G) Epigenesis True breeding “long” radishes were crossed with true breeding “round” radishes.The offspring of this cross resulted in 100% “oval” radishes. This type of inheritance is most consistent with _________ Marfan syndrome is caused by an autosomal dominant gene that has multiple phenotypic effects such as lengthened long...
