Chapter 10, Problem 22P

Two experimental varieties of strawberry are produced by crossing a hexaploid line that contains 48 chromosomes and a tetraploid line that contains 32 chromosomes. Experimental variety   1 contains 40 chromosomes, and experimental variety 2 contains 56 chromosomes.

Do you expect both experimental lines to be fertile? Why or why not?

How many chromosomes from the hexaploid line are contributed to experimental variety 1 ? To experimental variety   2 ?

How many chromosomes from the tetraploid lines are contributed to experimental variety 1 ? To experimental variety 2 ?

A diploid plant is heterozygous for two linked genes, A and B. Crossovers between the two genes occurs in ~10% of meiosis. Multiple crossovers are never observed in one cell undergoing meiosis. What fraction of the gametes produced by this diploid plant are expected to be recombinant type? O 5% O 10% 2.5% 25%
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
A diploid plant is heterozygous for two genes on the same chromosome, A and B. Crossovers between the two genes occurs in 100% of meiosis. What fraction of the gametes produced by this diploid plant are expected to be recombinant type? 25% O 50% 0% O 100%
