In the silkworm of one breed, striped caterpillars weave white cocoons, while in the other, monochromatic caterpillars weave yellow cocoons. Silkworms of two breeds were crossed. All F1 caterpillars are striped and weave yellow cocoons. Determine: 1) which features are dominant; 2) what offspring can be expected from crossing F1 hybrids with homozygous butterflies, whose monochromatic caterpillars weave yellow cocoons.

1) Dominant characters – striped color of caterpillars and yellow color of cocoons, recessive – green color of caterpillars and white color of cocoons; 2) from the crossing of F1 hybrids with butterflies, whose monochromatic caterpillars weave yellow cocoons, one can expect offspring, whose striped caterpillars weave yellow cocoons, and offspring, whose monochromatic caterpillars weave yellow cocoons, in a 1: 1 ratio (genotypes AaBB, AaBb, aaBB, aaBb in a ratio of 1: 1: 1: 1).
