Heredity And Genetics
Settings
.
- 1.Heredity is best described as the -
- A.
Storage of waste materials produced by cells
- B.
Passage of genetic material from generation to generation
- C.
Communication of information between an organism's cells
- D.
Production of energy for use in an organism's cells
- 2.Genes are located in which part of the cell?
- A.
Endoplasmic reticulum
- B.
Chromosome
- C.
Cytoplasm
- D.
Lysosome
- 3.The primary function of the chromosome is to -
- A.
Store the genetic instructions needed to specify traits.
- B.
Release energy by breaking down food molecules.
- C.
Transport waste materials rapidly out of the cell.
- D.
Relay messages between different cells in animals.
- 4.Which of the following cell organelles contains chromosomes?
- A.
Vacuole
- B.
Ribosome
- C.
Mitochondria
- D.
Nucleus
- 5.An organism inherits its genetic instructions from its -
- A.
Environment
- B.
Offspring
- C.
Parent(s)
- D.
Food source
- 6.What is the proper order from largest to smallest?
- A.
DNA --> Nucleus --> Chromosomes --> Cell --> Genes
- B.
Genes --> DNA --> Chromosomes --> Nucleus --> Cell
- C.
Cell --> Nucleus --> Chromosomes --> DNA --> Genes
- D.
Genes --> Cell --> Nucleus --> Chromosomes --> DNA
- 7.Recessive traits are expressed (are seen in an organism) -
- A.
In 1/4 of the offspring produced.
- B.
Always in all members in the population.
- C.
Only when the dominant allele is not present.
- D.
If the trait is carried by the male.
- 8.A scientist studying pea plants discovered that when he crossed tall male pea plants with tall female plants most of the offspring pea plants were tall. Only a few offspring pea plants were short. What does this tell you about the height of pea plants?
- A.
Pea plants grow taller in the sun
- B.
Pea plant height is controlled by heredity
- C.
Pea plant height is not controlled by heredity.
- D.
Pea plants are never short.
- 9.The table lists traits and whether they are recessive or not for two parents. Based on the data table, if the parents reproduce and create offspring, the offspring will -
- A.
Most likely have brown hair and definitely not have blue eyes.
- B.
Definitely have brown hair and definitely have blue eyes.
- C.
Definitely have red hair and most likely have brown eyes.
- D.
Most likely have red hair and maybe have blue eyes.
- 10.In humans, the gene for brown eyes is dominant over the gene for blue eyes, which is recessive. If two blue-eyed parents have six children, how many of their children will have blue eyes?
- A.
Zero
- B.
Two
- C.
Four
- D.
Six
