Part 1: crossing beak color and tail-feather length cross a yyll (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). look at the number of genotypes of the f1 generation: yyll: 400 yyll: 100 yyll: 100 yyll: 400 (score for question 1: of 2 points) which offspring are the recombinant offspring in this cross?type your answer here.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
