*college level answer or below. minimum 250 words

Bryophytes were once the dominant land plants, then seedless vascular plants took over. Gymnosperms came after that but were replaced by Angiosperms. Discuss the adaptations of Angiosperms which has allowed this group to dominate the plant kingdom for the past 100 million years. Do you think Angiosperms represent the pinnacle of plant evolution or can you imagine adaptations in a hypothetical new group of plants which might supplant Angiosperms in the future? Explain.

18. Short hair in rabbits is governed by a dominant gene (L) and long hair by a recessive allele (l). Black hair results form the action of the dominant genotype (B_) and brown from the recessive genotype (bb). In a cross between homozygous short, black haired rabbit and a homozygous long, brown haired rabbit what are the phenotypic and genotypic ratios of the F1 and F2 generation.

You’re provided a lab protocol to perform a very short digestion of eukaryotic chromatin with micrococcal nuclease, which should result in DNA fragments of 200 base pairs. You setup the experiment but get called away suddenly and are gone for a length of time. When you return to complete the experiment and run the gel to visualize the samples, it shows 146 base pair fragments. Explain what occurred.
