1. Pea plants can
A. self-pollinate, but are not self-compatible C. only cross-fertilize
B. self-fertilize D. reproduce without pollination
2. Advantages to using the garden pea for Mendel's experiments included all listed below except
A. true-breeding varieties were scarce.
B. he could expect to observe segregation of traits among the offspring.
C. they have relatively short generation time.
D. sex organs of the pea are enclosed within the flower.
3. Phenotype refers to an organism's:
A. genetic code B. physical appearance C. ratio D. parents
4. Two true breeding parents are crossed similar to Mendel's P generation. A tall plant is crossed with a short plant.
What is the expected outcome for the F1 generation?
A. all short C. all medium height
B. all tall D. half tall, half short
5. An organism with two identical alleles for a trait is called:
A. heterozygous B. homologous C. homozygous D. polyploid
6. Which refers to the different forms of genes representing a certain trait?
A. allele B. chromosome C. hybrid D. locus
7. What do you call a combination of the dominant and recessive genes present in the cells of an organism?
A. genotype B. lectotype C. neotype D. phenotype
8. Which of the following is NOT a Mendelian law of inheritance?
A. In every organism, there is a pair of factors that control the appearance of a particular trait.
B. The first filial generation does resemble either parent. Therefore, no allele is dominant over the other.
C. During gamete formation, the pair of factors segregates or separates from each other.
D. During fertilization, the genes come together again to form new combinations.
9. What is a monohybrid cross?
A. A cross using a single factor or character.
B. A cross using two factors or characters.
C. A diagram that determines the possible combinations of traits.
D. None of the above
10. This principle states that alleles separate during gamete formation:
A. principle of multiple alleles C. principle of independent assortment
B. principle of dominance and recessiveness D. principle of segregation
