What You Need to Know:
You should be able to:
explain how to calculate probability
explain the product law of probability,
differentiate between gene and allele,
differentiate between haploid and diploid
explain the terms genotype and phenotype and how they relate to blood types and corn kernels,
distinguish between homozygous and heterozygous,
calculate the expected ratio in corn kernels for a dihybrid cross,
explain who can give blood to whom,
explain the role of Rh factor in blood types and how it applies to erythroblastosis fetalis,
explain agglutination and blood types and how blood types are examples of multiple alleles,
predicct who can and cannot be the father of a child based on blood types, and
explain some common human genetic traits and their dominance in the population.
Exercises: Fill in the Blank.
The probability of some event is always between and .
If I flip a coin five times, and it comes up heads each time, what is the probability that the sixth toss will result in heads?
What is the probability that if I flip a coin three times, it will come up heads all three times?
What trait is dominant in corn kernels for color? .
If the genotype is PP, then we would say the organism is . (homozygous, heterozygous)
If someone says purple is dominant over yellow in corn kernels, they are referring to expression. (genotypic, phenotypic)
AaSs would represent a individual. (homozygous, heterozygous) and it also represents a cross. (monohybrid, dihybrid)
In the first filial generation of your corn kernel cross, how many kernels should be purple? (Assume the parents were pure strains of purple and nonpurple.) .
Out of 600 kernels, in a dihybrid cross of a first filial generation, how many kernels should be purple and smooth?
Can AB blood types donate blood to O people? (yes or no) .
Can parents of A and B blood types produce a child of AB blood type? (yes or no) What would be the probability of that event occuring?
In order for erythroblastosis fetalis to occur, what must the mother of the child be as far as Rh factor? .
Exercises: Multiple Choice. Select the Best Answer.
Out of 200 corn kernels from a dihybrid cross (second filial generation), how many should be nonpurple and wrinkled?
(1) 112
(2) 125
(3) 37.5
(4) 66.6
(5) 12.5
The probability that the first two children of a mating will both be boys is:
(1) 1/2
(2) 1/4
(3) 1/8
(4) 1/64
(5) cannot be determined from this information
What blood type can a child not be if the parents are AO and BB?
(1) AB
(2) BO
(3) AO
(4) BB
(5) both 3 and 4 are correct
If a person has B blood type, what antibodies do they have?
(1) A
(2) B
(3) A and B
(4) no antibodies for blood type are present
(5) Cannot be determined from this information.
Whose discovery about clumping lead to the four blood types?
