4. You cross individuals with the following Genotypes, AaBbDdEeFFGg & AaBbDDEeFfGg. Predict the proportion of offspring that would show the following Phenotype or Genotype? A) all Dominant Phenotypes, B) the Genotype: AabbDdEeFfgg, C) the Genotype: AABbDdEeFfgg, D) the Genotype: aaBbddEeffGg, & E) all Recessive Phenotypes. 5.

In a certain plant species, inheritance of fruit size is controlled by four genes, each of which has two alleles that show incomplete dominance and each of which contributes equally to an individual’s phenotype. Plants with the largest fruits have the genotype AABBCCDD, while those with the smallest fruits have the genotype aabbccdd. a) How many possible genotypes for fruit size are there in this species? b) Based on genotype alone (ignoring environmental factors), how many possible phenotypes for fruit...

Evaluating your phenotypes and genotypes and testing a genetic hypothesis in corn There are two activities in this write up. In the first, you will evaluate your phenotypes and genotypes and relate them to parental phenotypes and genotypes. In the second, you will test a hypothesis using a monohybrid cross in corn and carry out a Chi-squared analysis. For the write up, please copy and paste the remaining part of the Lab document into a new document, then fill in...

Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...

Human Mendelian Traits Mendelian Traits are those traits which follow Mendel's rules of only 2 possible versions of a gene(1 dominant, 1 recessive). There are only a few examples of this in humans. 1. Circle the heterozygous dominant genotypes: AA Aa aa YyYY W Re RR 2. Circle the homozygous recessive genotypes: AA Aa aa YyYY V ir Rr RR 3. Use the chart below to determine your phenotype (observable characteristic) and possible genotype(s) (a pair or pairs of alleles)....

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...

15. The gene for petal color in a flower has incomplete dominance, so that individuals with two Al alleles (AIA) are red, individuals with two A2 alleles (A2A2) are white, and individuals with one of each allele (AIA2) are pink. In a cross between a red flower and a white flower, what is the probability of getting a pink offspring?
