Kernel color in wheat is controlled by 2 pairs of genes (AABB). Determine the color of each offspring with the following genotypes: (Note: 4 alleles – red; 3 – medium red; 2 – intermediate red; 1 – light red; 0 – white). CAPITAL letters only and with spaces when applicable. AABb - AaBb - AABB - aaBb - aabb -
Locus A has two alleles (A and a) while locus B has two alleles (B and b). The recombination frequency between locus A and locus B is 17%. A F1 heterozygote in trans-configuration is mated with an aabb individual. What are the expected phenotypic percentages in the resulting progeny? Round your percentages to the nearest tenths and in the following format, replacing the "0.0" with your percentages:
The eye ring color in wood ducks is under the control of a single, sex linked gene. The dominant allele (R) produces a white eye ring and the recessive allele (r) produces a green eye ring. Provide the results to the following crosses (note birds have ZZ:ZW sex determination). a) Provide the phenotypes and phenotypic ratios of a cross between a female with a white eye ring and a male with a green eye ring. b) Determine the phenotypes and phenotypic ratios for a cross involving an F1 female and an F1 male from the above cross.

A diploid plant has red flowers, heavy seeds and large leaves. The plant is a heterozygous for the following three genes:flower color (gene “F”),seed weight (gene “S”),and leaf size (gene “L”). This plant is testcrossed to a plant, which has white flowers, light seeds, and small leaves, the progeny of the testcross is as follows: 222 Red, heavy, large 228 White, light, small 224 Red, heavy, small 226 White, light, large 24 Red, light, large 26 White, heavy, small 25 White, heavy, large 25 Red, light, small Based on this results, which of the following statement is correct? Question 9 options: All three genes are on different chromosomes. Genes S and L are linked, while F assorts independently. Genes F and S are linked, while L assorts independently. Genes F and L are linked, while S assorts independently.
What is the distance between the orange eye color locus and the STRs, how frequent will you expect to get recombinant progeny with orange eyes? What would the probability of this marriage be producing children with orange eyes?
Two genes, m (apical meristem) and r (starburst rhizosomes), are linked on chromosome #5 in pea plants. Both genes are recessive to wild type and found to be 8 MU apart. If a wild type heterozygote is test- crossed, and produces 91 apical meristem plants and 8 apical, starburst plants from a total of 200 plants were produced, how many wild type plants will be produced? 4 8. 12 16
In soybeans, rough seeds (g) are recessive to wild-type glossy seeds (G), and blue flowers (p) are recessive to wild-type purple flowers (P). Two true-breeding plants with contrasting phenotypes for seeds and flower color were crossed (you will determine the parental phenotypes and genotypes as part of this question). The F1progeny are all wild-type. An F1 plant is then testcrossed and the following are obtained: Rough seeds, purple flowers 245 Glossy seeds, blue flowers 223 Rough seeds, blue flowers 18 Glossy seeds, purple flowers 25
A complementation analysis was performed using Drosophila which normally have black wings. Six mutants for clear wings were discovered. The mutants were bred in a complementation test to produce the following: Mutant 2 4 # 1 1 1 1 2 1 1 1 1 1 1 4 1 1 Where a "0" (zero) means clear wing offspring and a "1" (one) means wildtype (black wing offspring). How many genes can you identify that affect the production of wing colour in Drosophila? O a. 3 O b.4 О с. 5 O d. 6 O e. none of the above 3. 5
