Presentation on theme: "3 rd MP Snow Day Review. My recommendation The powerpoint is set up to help you practice your knowledge of this marking period. This is not everything!"— Presentation transcript:
My recommendation The powerpoint is set up to help you practice your knowledge of this marking period. This is not everything! (Maybe 80% of what is expected for the test.) The “bolded slide” asks a question or states a problem followed by the answer. My recommendation is to have a piece of paper ready and write the answer then check it. Do not use your notes or textbook. IF YOU HAVE ANY QUESTIONS, PLEASE CONTACT ME: Stephanie_doodigian@hcpss.org Complete all the slides and follow the directions on the last slide.
An allele is a form of a gene. You get 2 alleles for a trait, one from each parent. An example would be- An allele for eye color: You have blue eyes, the dominant allele, from your mom, and you have the allele for brown eyes in your genotype. The allele for brown eyes is from your dad. A dominant allele is the allele that is shown in a person's phenotype. A recessive allele is not visible, but is in a person's genotype. Both dominant and recessive alleles can be passed to the individual's offspring.
If a trait is sex-linked, the trait occurs more commonly in…
MALES! A particularly important category of genetic linkage has to do with the X and Y sex chromosomes. These not only carry the genes that determine male and female traits but also those for some other characteristics as well. Genes that are carried by either sex chromosome are said to be sex linked.
What is the process (or steps) of protein synthesis? Beginning with gene…
What are the steps of the cell cycle? When does replication occur?
G1 Synthesis – replication of DNA G2 MITOSIS – cell division Cytokinesis http://www.cellsalive.com/cell_cycle.htm
Mutations are transmitted to next generations if they are present in which type of cells? Sex cells or body cells?
Sex cells. Sex cells form gametes. The gametes fuse together to form a new offspring. So unlike any other cell (like body cells or blood cells), sex cells only are passed on to the next generation (that is via fertilization). Only sex cell mutations are passed on to future generations.
The process of choosing organisms with the most desirable traits to mate is known as…
