i need help with this questions ..
1. attached earlobes are dominant over free hanging earlobes. Attached---A Free--a cross a homozygous dominant person with a homozygous recessive person. Work out the punnet square and give the genotypic and phenotypic ratios from this cross.
2. Cross a heterozygous individual with another heterozygous individual for earlobes(Hint look at question 1.) Work out the punnet square and give the genotypic and phenotypic ratios from this cross.
3. A male with black hair, homozygous dominant, has offspring with a blonde woman
What are the ratios of genotypes found in the offspring?
4. a tall pea plant, heterozygous, is crossed with a short pea plant, short being the recessive trait. What are the phenotype ratios of the offspring?
5. Red carnations (R) White Carnations(R') Show your knowledge of incomplete dominance by crossing a Pink carnation(heterozygous) with a White carnation(homozygous white). Work out the punnett square and give the genotypic and phenotypic ratios from this cross.
6. Cross a two pink carnations. Work out the punnet squares and give the genotypic and phenotypic ratios from this cross( Hint look at question 5)
7. Show your knowledge of blood types; cross a person that has AB blood with a person that has O Blood. Work out the punnet squares and give the phenotypic ratio from this cross.
8. Show your knowledge of blood types; cross a person that is heterozygous A blood with a person that is homozygous B blood. Work out the punnet squares and give the phenotypic ratio from this cross.
9. Show your knowledge of blood types cross a person that has AB Blood with a person that is homozygous B blood. Work out the punnet squares and give the phenotypic ratio from this cross.
10. Show your knowledge of sex-linked traits; cross a female carrier for color-blindness with a male that is color-blind. Work out the punnet square. What is the chance that they will have a color-blind male?
