Direction: Choose the best answer and write the letter of your choice.
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
B. all tall C. all medium height D. half tall, half short.
5. If a plant that has round seeds has a parent that has wrinkled seeds, what is its genotype?
(Assume that round is dominant.)
A RR
B. Rr
C.m
D. RrWw
6. An organism with two identical alleles for a tralt is called:
A heterozygous
B. homologous C. homozygous D. Polyploidy
7. Which refers to the different forms of genes representing a certain trait?
A allele
B. chromosome
C. hybrid
D. Locus
8. 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
9. If you crossed two heterozygous plants, how many of the offspring will also be heterozygous?
A All
B half
D. WA
10. 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 aparticular trait
8. 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​
