How many chromatids does the tetraploid line have during prophase 1? How many chromosomes would the tetraploid gametes have? How many chromosomes does the seedless progeny have? Question 10 options: A) 88, 22, 33 B) 44, 88, 66 C) 22, 44, 44 D) 22, 44, 88 E) 44, 88, 44 How many unique alleles for a given gene can a tetraploid line have? Question 11 options: A) 1 B) 2 C) 4 D) 8 E) 16 In an animal with two homologous chromosomes (represented as A, a, B, b) which of the following is a potential genotypes for its gametes? Question 12 options: A) AaBb B) AABB C) Aa D) Ab In pea plants, purple flowers are dominant to white flowers. If you have a purple plant, and want to determine if it’s heterozygous or homozygous dominant, you would perform a testcross with which genotype? Question 13 options: A) p B) P C) pp D) PP E) Pp In cucumbers, orange fruit color ( R ) is dominant over cream fruit color ( r ) . A cucumber plant homozygous for orange fruit is crossed with a plant homozygous for cream fruit. The F1 are intercrossed to produce the F2. What will be the ratio of genotypes in the F2? What will be the ratio of phenotypes? Question 14 options: A) 1:2:1, 3:1 B) 3:1, 1:2:1 C) 1:2:1, 1:2:1 D) 1:2:1, 3:1 • Show less
