Genetics Practice (stop using this one)

Master genetics with Punnett squares & trait practice!

Place the following genotypes in the correct column of "homozygous" or "heterozygous". Homozygous TT aa GG zz Heterozygous Hh Dd Ee Ww Need to know information - Dominant or Recessive Tall pea plants (T) are dominant to short (tt).Yellow peas (Y) are dominant to green (yy).WIdow's peak (W) is dominant to a straight hairline (ww).Brown eyes (B) are dominant to blue eyes (bb). Genotype TT Ww Bb yy Phenotype Widow's Peak Tall pea plant Green pea Brown eyes What would the phenotype be for the following genotypes?Make sure you have looked at the Dominant or Recessive reading before answering these. A pea that is yy would be green in color.A TT pea plant would be tall.A person with Ww would have a Widow's peak.A person with Bb would have brown eyes. An organism's _ describes its genetic composition. An organism's _ describes its appearance or observable characteristics. species; heredity phenotype; genotype genotype; phenotype heredity; species Set up the following Punnet square. A homozygous wrinkled seed plant is crossed with a heterozygous round seed plant. Need to know - Round seeds are dominant to wrinkled seeds, put the first phenotype mentioned on the top! R - round allele, r - wrinkled allele r r Rr r R Rr rr rr The genotypes of the offspring are 100% round 50% round 50% wrinkled 100% rr 50% Rr 50%rr The phenotypes of the offspring are 100% round 50% round 50% wrinkled 100% rr 50% Rr 50%rr Set up the following Punnet square. A person homozygous for brown hair reproduces with a person with blond hair Need to know - Brown hair (B) is dominant to blond (b), put the first phenotype mentioned on the top! B b Bb B b Bb Bb Bb The genotypes of the offspring are 100% Brown haired 50% Brown haired 50% Blond 100% Bb 50% Bb 50%bb The phenotypes of the offspring are 100% Brown haired 50% Brown haired 50% Blond 100% Bb 50% Bb 50%bb Set up the following Punnet square. Two heterozygous short-haired rabbits are crossed. Need to know - long-hair is recessive to short-hair in rabbits, put the first phenotype mentioned on the top! L - short-haired allele, l - long-haired allele l l Ll L L LL Ll ll The genotypes of the offspring are 100% short-haired 75% short-haired 25% long-haired 50% short-haired 50% long-haired 50% Ll 50% ll 25% LL 50% Ll 25% ll 100% Ll The phenotypes of the offspring are 100% short-haired 75% short-haired 25% long-haired 50% short-haired 50% long-haired 50% Ll 50% ll 25% LL 50% Ll 25% ll 100% Ll I bought a black female rabbit from a local breeder. Surprise! She had 10 kits. Four of them were black and six were albino. I called the breeder and she had no idea what male rabbit could have been the father. (Black is dominant to albino in rabbits.) C is used for full-color in rabbits, and c is used for the albino trait.The female rabbit is most likely Cc (genotype).The male rabbit is most likely cc (genotype).
