Question

CA inf со w Construct a personal record of your phenotype and possible genotypes for the traits condition, you will know with certainty your genotype (...hh). If your phenotype is the dominant condition, you may not know if you are homozygous dominant of heterozygous. If you don't know about your parents or children-Just indicate you could be either by recording both the homozygous dominant and heterorygous genotype (i.e., HH, Hh) TRAIT Your Phenotype Your Genotype Dimple Chin D-Dimples d-no dimples Tongue Roller R-Can roll tongue r cannot roll tongue Ear Morphology (shape) E-free carlobes e rattached earlobes Widow's Peak W-widow's peak W-straight hairline Interlocking fingers F-Left Thumb on Top f-Right Thumb on Top Bent Little Finger B-bent finger b=straight finger Hitchhiker's Thumb H=straight thumb h-hitchhiker's thumb Long Palmar Muscle L=3 tendons 1=2 tendons Pigmented Irises (eve color) P-pigmented (anything but blue) panot pigmented a.

Answer 1

pe is Bot know if you are homozygous dominant or ygous. If you don't know about your parents or children just indicate you could be either -- by recording both the homozygous dominant and heterozygous genotype (i.e., HH, Hh) Your Phenotype Your Genotype dd no dimples roller RR or Rr free EE or Ee straight WW TRAIT Dimpled Chin D-Dimples d no dimples Tongue Roller R-Can roll tongue cannot roll tongue Ear Morphology (shape) E-free carlobes e attached earlobes Widow's Peak W-widow's peak w-straight hairline Interlocking fingers F-Left Thumb on Top f-Right Thumb on Top Bent Little Finger B-bent finger b=straight finger Hitchhiker's Thumb H=straight thumb h-hitchhiker's thumb Long Palmar Muscle L=3 tendons 1=2 tendons Pigmented Irises (eye color) P-pigmented (anything but blue) p=not pigmented left on top FF or Ff bent BB or Bb hitchhiker HH or Hh 3 muscles LL or LI pigmented PP or Pp a. For the traits observed, was the dominant gene expressed most often? tongue roller, ear morphology, interlocking fingers, bent little finger, thumb, muscle, pigment b. For which traits was this not true? dimples, widows peak c. How would you explain your results? bcz dominant allele can express itself in the heterozygous condition, hence it is mostly observed
