D. All of these
Crossing over helps promote
A. male genotype
B. genetic variation
C. DNA replication
What is Mendel’s Law of Independent Assortment?
A. If the recessive allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
B. The passing of allele of one trait does not affect the passing of allele of another trait.
C. If the dominant allele is passed for one trait, then it is more likely that the dominant allele will be passed for the other trait.
D. If the dominant allele is passed for one trait, then it is more likely that the recessive allele will be passed for the other trait.
What is one reason why we need meiosis?
A. To double the number of chromosomes going into sex cells
B. To halve the number of chromosomes going into sex cells
C. To triple the number of chromosomes going into sex cells
D. To not change the number of chromosomes going into sex cells
Which of the following is NOT a genotype?
B. a trait
D. homozygous recessive
Is it possible for a female to express a Y-Linked trait, and why or why not?
A. Yes, Because they have room on their X Chromosome for it
B. Yes, Because they can take it from the father
C. No, Because the copy on their X Chromosome will overpower the copy on their Y chromosome
D. No, Because they lack a Y chromosome
If B = brown hair and b = blonde hair, what is the probability of brown hair?
Which of the following genotypes is homozygous dominant?
What do we call the result of the genotype (for example, the color of the peas)?
A. Visible traits
C. Genotype 2
Hemophilia is a recessive x-linked disorder.
Which genotype represents afemale who is a carrier for hemophilia?
What is the probability of heterozygous offspring?
A human being has a somatic cell that has 46 chromosomes. What is the haploid number found in a gamete?
What is a phenotype
A. The genetic make up (code)
B. The physical trait

C. Golden ratio
D. Fibonacci sequence
Why were pea plants perfect a study on Heredity?
A. Pea plants were easy to care for and produced many offspring
B. The Traits were distinct and easy to identify
C. One gene controlled one trait. (i.e. it was simple)
D. All of These
A male shark has 40 chromosomes in each of its sex cells. How many would be present in its body cells?
Males are more likely to suffer from a sex-linked disease or disorder because
A. males are the weaker sex
B. males have less DNA
C. males have 1 X chromosome, so the disorder is more likely to be expressed

The genotype for a yellow plant is…
D. all of the choices result in yellow
