Dragon Key Upper case letter represent dominant alleles; lowercase letters represent recessive allelesN = LONG NECK n = short neckE = RED EYE e = white eyeH = HORN PRESENT h = horn absentF = FIRE BREATHING f = not fire breathingG = GREEN BODY g = grey bodyL = LONG TAIL l = short tailS = SPIKES ON END OF TAIL s = no spikes on end of tailR = RED WINGS r = yellow wingsT = THREE TOES t = four toesW = YELLOW BELLY w = white bellyB = BLACK TAIL SPIKES b = red tail spikesK = FRECKLES k = no frecklesX = X chromosome / no ear frills (XX = female)Y = Y chromosome / ear frills present (XY = male) 1. What letters are used to represent wing color? ____________________________________________ 2. What letters are used to represent neck length? ____________________________________________ 3. The letter Y is used as a symbol to represent ____________________________________________ ____________________________________________ 4. The letter e is used to represent _______________________________________________________ An upper case, or capital, letter is used to represent a dominant trait. A lower case, or small, letter is used to represent a recessive trait. Dominant traits completely mask and/or suppress recessive traits. Refer to the key, and answer the following questions. 5. List six dominant traits shown in the key. _________________________________________________ __________________________________________________________________________________________________________________________________________________________________________ 6. List six recessive traits shown in the key. _________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________   Dragon Genetics Worksheet #2 Would Someone Please Take Charge?  INSTRUCTIONS Using the key from Worksheet #1 as a reference, fill in the missing symbols for alleles (genotypes) or descriptions of physical appearance (phenotypes) in the table below. The first two rows are done for you. Remember, dominant traits appear when either one or two copies of the dominant allele are present. For example, NN and Nn both cause the dragons neck to be long. Only in the case of nn would the dragons neck be short because no dominant allele for a long neck is present.
