Intro to Genetics Vocabulary

Master genetics terms like genotype and phenotype! Practice sorting alleles and traits.

Place the following genotypes (the letters scientists use to name traits,) in the correct column of "homozygous" or "heterozygous". ***Remember homozygous has the two oo that are the same size, so homozygous is when both alleles are EXACTLY THE SAME (BB or bb). Heterozygous is when you have one capital allele and one lowercase allele. They are NOT THE SAME (Bb).*** Homozygous bb GG RR zz CC AA Heterozygous Ee Ff Mm Ww Please sort these letter and words into the correct category. ***Remember a phenotype is the actually WORD scientists call the trait (think phonics!!) And Genotype is the letters (2 alleles) that scientists give to traits. Genotype Gg TT Ww Hh Phenotype Tall Green Curly Hair Dimples Freckles Attached Earlobes Please sort these genotypes into Dominant and Recessive. ***Remember Dominant needs at least 1 capital letter because capital letters are the boss (Ss or CC)!!! Recessive traits are less common and do not have a boss letter. Both alleles (letters) must be lowercase (gg or ee). Dominant TT Ss Qq VV Jj Recessive kk oo xx mm ww
