Cards in this deck (6)
- 12 Guinea pigs breed. One has a cream coat which is recessive (b). The other has a black coat (B). Is it possible to produce a cream colored coat? (cream is recessive).Yes, if the black coated guinea pig is heterozygous and not homozygous they can produce cream coloured offspring.
- 2In peas the allele for purple flower colour is (P) dominat over the allele for white. Cross a purebred tall purple plant with a purebred dwarf plant.All offspring would be heterozygous with a genotype of PpTt and a phenotype of purple and tall.
- 3Black is dominant in guinea pigs while short hair is dominant to long. Cross 2 heterozygous black, heterozygous short guinea pigs. Determine the frequency of having brown pigs with short hair.Out of 16, 3 will be brown with short hair.
- 4How is sex determined in mammals?Sex is determined by the 23 chromsome. 2 X chromosomes results in a female. An X and a Y is male.
- 5What are the chances a colourblind man will have a colourblind son if he has a child with a woman with no history of colourblindness?He will not have a colourblind son
- 6What type of blood can a type A receive? Which blood types can a type 0 receive?Type A: A and O
Type O: O
