Reproduction & Inheritance Review 7th Grade Core Mastery Tracker Standard and Objective STANDARD IV: Students will understand that offspring inherit traits that make them more or less suitable to survive in the environment. Objective 1: Compare how sexual and asexual reproduction passes genetic information from parent to offspring. Essential Questions Got it. Almost Not yet a. Distinguish between inherited and acquired traits. (3) b. Contrast the exchange of genetic information in sexual and asexual reproduction (4) c. Cite examples of organisms that reproduce sexually (3) d. Compare inherited structural traits of offspring and their parents. (3) Which characteristic would you expect a puppy to acquire from its owners? A. number of legs B. eye and hair color C. ability to wag its tail D. to come when called Both parents of a Siamese cat have green eyes. Their offspring also have green eyes. This would be an example of a. an acquired trait b. an inherited trait c. a learned trait d. a found trait Kelly’s mom is a concert pianist. People keep telling Kelly that she will also be a great pianist one day because she will “get it from her mom”. How could you describe this statement? a. True - piano playing is an inherited trait b. True - piano playing is an acquired trait c. Inference - piano playing is an inherited trait d. Inference - piano playing is an acquired trait A piece of a geranium plant is cut and placed it in a jar of water in the window. Several weeks later the piece has grown into a new plant. Which of the following is true about the genetic relationship between the first plant and the new one? A. The two plants are different genetically. B. The two plants are slightly different genetically. C. The two plants are genetically identical. D. There is no way to know the genetic relationship. Which of the following is a structural trait of all living things? A. being made of cells B. having two legs C. having hair D. having two types of teeth A flower is a structure that allows which type of reproduction for the plant? A. Nonsexual B. Sexual C. Unisexual D. Asexual You are given 3 unknown organisms labeled A, B, C. When looking at the DNA of the three unknown organisms, you find that they all have the exact same sequence of DNA. Which statement below is the most logical explanation? a. Organisms A, B, and C were reproduced asexually from a common parent b. Organisms A, B, and C were reproduced sexually from a single pair of parents c. Organism A and B are the parents of C. d. Organism A, B, and C are unrelated Which of the following is an example of sexual reproduction? a. division of one amoeba into two c. joining of egg and sperm b. d. growth of an organism one cell splitting to form two cells Bacteria reproduce asexually by dividing in two. If you were to examine the genetic material of two bacteria that had just been reproduced from the same parental cell, how would their genetic material compare? (Assume no mutations occur) a. about 50% the same b. about 65% the same c. 100% the same d. completely different List two advantages of reproducing asexually. When fir trees produce cones and seeds, this is an example of what type of reproduction? If brown eyes (B) are dominant over blue eyes (b), then a heterozygous genotype for brown eyes would be _______. ( Hint: Latin root words…homo=same hetero=mixed) If I am a race horse breeder, and I want to produce a faster race horse, should I spend more time training my horse or breed two fast horses together? Explain. What type of reproduction has occurred when an organism is produced from only one parent? A. Nonsexual B. Sexual C. Unisexual D. Asexual Which type of reproduction results in offspring that are most different from the parent organisms? A. Nonsexual B. Sexual C. Unisexual D. Asexual Rank these in order of size, largest to smallest: adenine molecule, gene, strand of DNA, cell nucleus, chromosome What is an allele? If a plant can reproduce both sexually and asexually, what would be the most advantageous for offspring survival during a drought? Why are mules sterile? Match the following vocabulary words with their definitions: acquired trait a- type of reproduction exhibited by aspen trees asexual reproduction b- type of reproduction exhibited by chickens budding c- something learned or gained after birth cloning d- a characteristic that is “programmed” at birth cytokinesis e- having two alleles that are the same genotype f- the outward expression of genetic traits (looks) inherited trait g- the process of cell duplication mitosis h- when a cell pinches in ½ to form 2 separate cells phenotype i- form of asexual reproduction exhibited by hydra sexual reproduction j- form of asexual reproduction used to create Dolly k- The genetic code of an organism
