A rice breeder obtained a triple heterozygote carrying the three recessive alleles for albino flowers (al), brown awns (b), and fuzzy leaves (fu), all paired with their normal wild-type alleles. This triple heterozygote was testcrossed. The progeny phenotypes were :

170 wild type
150 albino, brown, fuzzy
5 brown
3 albino, fuzzy
710 albino
698 brown, fuzzy
42 fuzzy
38 albino brown

a. Are any of the genes linked? If so, draw a map labeled with map distances.
b. The triple heterozygote was originally made by corssing two parental lines. What were their genotypes?

The construction of phylogenetic trees is a mapping out the proposed divisions and common ancestors of all living species. traditionally, these trees have been built using morphological data, such as appearance and embryology. recently, it has been possible to construct these trees using molecular data. phylogenetic trees based on different types of information agree with each: that there is strong evidence of a real underlying common descent. this phylogenic tree is composed based on molecular data (rrna). what statements can we infer are true about the organisms throughout the tree? because the tree is rooted, all branches share a common ancestor. all organisms have some sort of cellular structure/organization. all eukaryotes evolved from bacteria. since the organisms contain rna, they share the same dna. if the organisms contain rna, the share the same four nitrogen bases.

Which macromolecule catalyzes chemical reactions this be considered enzyme chemical reactions thus he considering enzymes

This is collection of data made by comparing objects in standard units. in science, the units are metric.
