Meiosis Independent Practice

Which of the following are true about human female gametes?

• The gametes are not identical.

• The chromosomes are all the same.

• The gametes contain 23 chromosomes each.

• The gametes contain 46 chromosomes each.

• The gametes are identical.

In ​ (a)   reproduction, an organism will inherit its genetic information from two different parents. This helps increase genetic ​ (b)   . In ​ (c)   reproduction, an organism will inherit its genetic ​ (d)   from one parent. The new offspring will have the same genetic information as its parent.

• sexual
• variation
• asexual
• information

The production of egg and sperm cells is necessary for sexual reproduction because —

• it increases the number of chromosomes so that the gametes can combine, giving the organism a complete set of chromosomes

• it reduces the number of chromosomes so the gametes can combine, giving the organism a complete set of chromosomes

• it increases the number of developing offspring

• it decreases the number of developing offspring

Crossing over occurs during meiosis and contributes to genetic variation in sexual reproduction. The diagram shows part of the process of meiosis.

Click on the stage of meiosis where the 'crossing over' takes place.

Meiosis is critical to sexual reproduction because it is the mechanism that —

• reshuffles the genes in gametes.

• combines the genes in diploid cells.

• deforms the genes in prokaryotic cells.

• creates the genes in viruses.

The diagram shows a process that can affect chromosomes during meiosis.

• how new combinations of traits originate in offspring

• why parents produce genetically identical offspring.

• why some cells become specialized in offspring.

• how cell differentiation occurs in offspring.
