Name Date Objective Material Inheritance of Trait Comic trip A Genetic Activity Deign a comic trip that explain how certain human genetic characteritic are paed from parent to offpring Plain white paper Marker and other art upplie Background Activity/Lab 7 3 Gene found on chromoome determine the hereditary trait of living thing. The thouand of different gene found in a ingle organim account for the wide variety of trait that offpring can expre. In the body cell of a human being, chromoome are found in pair; however, the ex cell (egg and perm) have only 23 chromoome half the number other body cell have. When an egg and perm unite, the zygote (fertilized egg) ha 46 chromoome 23 from the mother and 23 from the father. You may have noticed individual with a pace between their two front teeth. The trait that produce a pace between the front teeth i dominant. Thi mean a child who acquire only one gene for a pace between the front teeth will have a pace between the front teeth, ince the preence of a dominant gene mak the preence of a receive gene. Ue to ignify the dominant trait for a pace between the two front teeth. Ue to tand for the receive trait for no pace between the two front teeth. The poible genotype of an offpring who ha a mother with the genotype and a father with the genotype i hown in the following Punnett quare: Page 1
Mother Gene The poible genetic combination for a child who ha a mother with the gene and a father with the gene are hown in the following Punnett quare: Mother Gene A child born to parent with thi genetic combination ha a 75 percent chance of having the gene that produce pace between the front teeth. The poible genetic combination for a child having a mother with the gene and a father with the ame gene are hown in the following Punnett quare: Mother Gene Page 2
A child born to parent with the above genetic combination ha no chance of having pace between the front teeth. ome other trait that can be examined with the aid of a Punnett quare are: Dominant Trait Rh-poitive blood Ability to roll tongue Middle digit ha hair Average height Huntington dieae ix finger on each hand Dark hair Curly hair Abundant body hair Early male baldne Pigmented kin, hair, and eye caly kin Abence of tooth enamel Abence of weat gland Brown eye Hazel or green eye Eyelid with Mongolian fold Nearightedne Farightedne Unattached ear lobe Broad lip Large eye Long eyelahe hort tature Dwarf tature Webbing of two or more digit Blood type A, B, and AB High blood preure Normal blood cell Receive Trait Rh-negative blood Lack of ability to roll tongue Middle digit ha no hair Dwarfed height Lack of Huntington dieae Five finger on each hand Light hair traight hair pare body hair No early male baldne Unpigmented kin, hair, and eye (albinim) Normal kin Preence of tooth enamel Preence of weat gland Blue or gray eye Blue or gray eye Eyelid with no fold Normal viion Normal viion Attached ear lobe Narrow lip mall eye hort eyelahe Tall tature Normal tature No webbing of digit Blood type O Normal blood preure ickle-haped blood cell Procedure 1. Create an informative comic trip howing the poible inheritance of a genetic trait. Your teacher will aign the trait. 2. Draw your comic trip on an unlined piece of 8½ 11" paper. Turn your paper o that the longet ide ret horizontally in front of you. Draw a line two inche from the top of the page. Place the title of your comic trip on thi Page 3
line. Divide the majority of the ret of the paper into two row, with four boxe of equal ize in each row (ee Figure 1). Thee boxe repreent the eight frame of your comic trip. 2 inche TITLE OF COMIC TRIP Figure 1 3. The eight frame of the comic trip hould: Ue a fanciful character() that you invent. The character will decribe how dominant and receive trait are inherited. how three generation (P 1,F 1, and F 2 ) of the inheritance of a trait. Ue a pedigree to help explain inheritance of the trait aigned to you. how one or more Punnett quare. Remember that expected reult and oberved reult are not alway the ame. Be intereting, informative, and fun to read. 4. Fill in your name and the date on the following evaluation form, and ubmit the form to your teacher with your comic trip. Page 4
