Reproduction Week 4

Certain species of whiptail lizards have only female individuals and no males. These lizards reproduce asexually. What is one disadvantage of asexual production for these lizards.

• A new population can be established by a single female in a short period of time.

• All members of the population are genetically very similar and less able to survive environmental changes.

• They are smaller than lizards that preproduce sexually.

• They are more likely to develop a variety of tail lengths.

The hydra is a very small, simple animal that lives in water. Hydras reproduce asexually by budding, a process in which a bud breaks off an adult hydra and floats away. Which of the following best describes a hydra bud?

• A hydra bud contains genetic material from its two parents.

• A hydra bud is genetically identical t the parent hydra.

• A hydra bud has different mutations than the parent hydra.

• A hydra bud has half as much genetic material as the parent hydra.

A group of students prepare the following table. Based on this information, which of the organism can reproduce offspring that are genetically identical to the parent organism?

• Ferns only.

• Amoebas and yeast only.

• Cats, hydras, frogs, and ferns only.

• Amoebas, yeast, hydras, and ferns only.

Three cousins have similar appearances but different face shapes. Which of these cell components are most involved in determining the basic shape of each girls face?

• Genes, chromosomes and nucleus.

• Cytoplasm, chloroplast, and chromosomes.

• Vacuoles, nucleus, and chromosomes.

• Chromosomes, chloroplast, and vacuoles.

The diagram shows the part of the cell. Which organelle stores the information that determines an individuals blood type.

• Organelle 1

• Organelle 2

• Organelle 3

• Organelle 4

A tiger cub has a pattern of stripes on its fur that is similar to that of its parent. Where are the instructions stored that provide information for the tigers fur pattern?

• In cytoplasm inside cells

• On genes within chromosomes.

• On the cell membrane

• In the mitochondria
