$500 Huntingtons disease is dominant. What are the chances that individual A will have Huntingtons? (assume both parents are homozygous)
MISC $100 A heterozygous organism is also called: Pure bred or hybrid
MISC $200 Blood type is an example of what type of dominance?
MISC $300 When roan cattle are mated, 25% of the offspring are red, 50% are roan, and 25% are white. Upon examination, it can be seen that the coat of a roan cow consists of both red and white hairs. This trait is one controlled by ____.
MISC $400 MANY genes go into human skin color and human height, these are known as what type of genetic traits?
MISC $500 Suppose an animal is heterozygous AaBb, and the traits are not linked. When meiosis occurs, what is the total number of possible combinations of gametes that can be made for these traits?
A white rabbit whose parents are both white, produces only brown offspring when mated with a brown mouse. Is the mouse: Homozygous or Heterozygous? AND Dominant or Recessive?
What is Homozygous Recessive
Alters the chromosome number
X linked recessive
The allele for colorblindness is recessive AND is on the X chromosome
