Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces colorless aleurone. The plant color (not the kernel color) is controlled by another gene with two alleles, Y and y. The dominant Y allele results in green color, whereas the homozygous presence of the recessive y allele causes the plant to appear yellow. In a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits, the following progeny were obtained: colored, green 88 colored, yellow 12 colorless, green 8 colorless, yellow 92 Explain how these results were obtained by determining the exact genotype and phenotype of the unknown plant, including the precise arrangement of the alleles on the homologs.

Coat color in labradors is determined by alleles of two unlinked genes, B and E. The coat colors of dogs with various genotypes are as follows: BB EE black Bb Ee black bb Ee brown (chocolate) Bb ee yellow bb ee yellow Which of the following cannot be inferred from this information? e and b alleles complement one another O e is dominant to b Oe is epistatic to b B is dominant to b
A is dominant over a and B is dominant over b. Genes A/a and B/b assort independently. The parental cross (P) is between true- breeding (homozygous) strains (AA bb x aa BB). The resulting F1 offspring would be [Select ] A F1 x F1 cross gives the F2 generation. The ratio of phenotypes in the F2 generation can be described as [ Select ] In the phenotypic ratio, what number refers to individuals that are: dominant for both traits?

Monohybrid Crosses and Punnett Squares Punnett squares are diagrams that can be used to predict the offspring that could result from combination of the gametes produced by two parents (or an organism that can self-) The from the gametes of one parent (eg, eggs) are placed on one axis of the Punnett square while alleles from the gametes of the other parent (egsperm) are placed on the other 1. Pea plants have two alleles for height T is the dominant allele and produces tall plants recessive allele and produces short plantsConsider two parental pea plants each have the genot and answer the following questions aWhat type of gametes can a plant with genotype produce? bAssign the maternal gametes to one axis in the Punnett square at right Assign the paternal gametes to one axis in the Punnett square at night Copyright 2017 Pearson Education
A cross was performed using Drosophila melanogaster involving a female known to be heterozygous for both ebony body and sepia eyes and a male known to be homozygous for both of these recessive traits. The following data was produced from the cross. Test these data to determine if they are significantly different from the expected phenotypic ratio. Remember to use the 5% level of significance Wild eye Wild body – 102, Wild eye Ebony body – 94, Sepia eye Wild body – 100, Sepia eye Ebony body – 93. Your answer should include the hypothesized cross in genotypes, the Chi-squared value, the critical value and whether you reject or do not reject.
Introduction: A dihybrid cross is a cross between individuals that involves two pairs of contrasting traits. To Predict the results of a dihybrid, cross all possible combinations of the four alleles from each parent must be considered. You will examine a dihybrid cross involving both color and texture. Purple (P), is dominate to yellow (p), and smooth texture (S) is dominant to wrinkled (s). Both parent plants are heterozygous for both traits. Review genetics and the use of Punnett squares in a biology text before doing this experiment.MATERIALS: Assume you have ear of Corn. You need a heterozygous X heterozygous 9:3:3:1, purple/yellow, starchy/sweet. PROCEDURE: From above please write out: The crop The parental (P) cross phenotype, genotype, gametes Cross between two F1 Selfed testcross 1. First let us use a Punnett square to examine the theoretical outcome of the Heterozygous X Heterozygous dihybrid cross. USE a Punnett square. REMEMBER: a phenotype is how the offspring will…
In com, colored aleurone (in the kernels) is due to the dominant allele R. The recessive allele r, when homozygous, produces colorless aleurone. The plant color (not the kernel color) is controlled by another gene with two alleles Y and y. The dominant Y allele results in green color, whereas the homozygous presence of the recessive y allele causes the plant to appear yellow. In a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits, the following progeny were obtained.
