RLA "Part 1" Review: Me Talk Pretty Genetics One Day

A GENETICS TERMINOLOGY REVIEW We will be having a "Chapter Quest" based on RLAs #1-6. You learned some difficult concepts, and a lot of new terms, so let's do some more practice. FIRST, go over RLAs #1-6 and record the vocabulary terms and examples on your STUDY GUIDE. THEN, Watch this video and complete the remaining questions. Genetics Vocabulary Match the word with the definition. Click the circlenext to the vocab word, and dragto the circle on the correct definition. genetics the study of how genes work and how genes are passed from parent to offspring. heredity This occurs when an organism gets its genetic information from a parent ratio a proportion homozygous alleles in a pair are the same (TT or tt) heterozygous alleles in a pair are different (Tt or Bb) gene the basic unit of heredity made of DNA that determines the kind of a traits you have Gregor Mendel the Austrian monk whose research on pea plants earned him the title "Father of Genetics" MATCHING VOCAB Matchthe vocab word with the definition! hybrid it means the thing same as heterozygous (Tt or Ww) genotype the genetic makeup of an organism represented by two letters (Bb, HH, etc) phenotype the physical appearance of an organism represented by descriptor words (blonde hair, green eyes, etc) trait an inherited characteristic (example: blood type) genome all of the genetic information that makes up an organism allele a version of gene that gives a specific characteristic (ex: a B-Type allele gives blood cells B-antigens dominant an allele that shows (expresses) with only 1 copy. It can sometimes hide other alleles. Represented with uppercase letter. recessive an allele that can only make a trait if someone has two copies. It can be hidden by a dominant allele, and is represented by a lower-case letter Write the Terms Carefully read the definitions, and then enter the correct term in the blank space.
