1.If a roan shorthorn is crossed with a white-coated shorthorn, what is the probability that the offspring will be a roan shorthorn?
Record a value from 0 to 1 rounded to two significant digits
2.A man of unknown genotype with blood type A and a woman with blood type O are going to have a child. Depending on the man's genotype, the minimum probability that the child will have blood type O is zero.
What is the maximum probability that the child will have blood type O?
Record a value from 0 to 1 rounded to two significant digits.
3.Snapdragons may be tall or short, and they may be red, white, or pink. The allele for short is recessive, and the alleles for colour display incomplete dominance. A plant, heterozygous for both these traits, was self-pollinated and produced 59 offspring.
How many of these 59 offspring would be expected to be both tall and pink?
4.Which of the following statements refutes the concept of incomplete dominance?
Select one:
a. Long-tailed cat X no-tailed cat → short-tailed cat
b. Frizzled chicken X normal chicken → mildly frizzled chicken
c. Black guinea pigs X white guinea pigs → all black guinea pigs
d. Red four o'clock X white four o'clock → pink four o'clock flowers
