In a newly isolated strain of fruit flies with semi-sterility, two previously linked loci show a new linkage relationship. This could be due to the fact that the new strain is
a. Homozygous for an inversion
b. Heterzygous for an inversion
c. Homozygous for a reciprocal translocation
d. heterzygous for a reciprocal translocation
e. Homozygous for a duplication
D) Heterozygous for the reciprocal translocation shows that the linkage in a new relationship obtained

In a newly isolated strain of fruit flies with normal viability of offspring, two linked loci map much closer than in other strains. This could be due to the fact that the new strain is a. homozygous for an inversion b. heterozygous for an inversion c. homozygous for a reciprocal translocation d. heterozygous for a reciprocal translocation e. Homozygous for a duplication

1. If two strains of true-breeding plants that have different alleles for a certain character are crossed, their progeny are called a. the P generation. b. the F1generation. c. the F2generation. d. F1crosses. e. F2progeny. 2. Mendel’s crossing of spherical-seeded pea plants with wrinkled-seeded pea plants resulted in progeny that all had spherical seeds. This indicates that the wrinkled-seed trait is a. codominant. b. dominant. c. recessive. d. Both a and b e. Both a and c 3. Segregation of...
