Types of Reproduction

What are the two types of reproduction?

What are the two types of reproduction?

sexual and asexual

What is a another name for sex cells?

Gametes

How many chromosomes does egg and sperm have?

23 chromosomes

What is an allele?

Alternative of a gene

What are the properties of asexual reproduction?

• only involves one parent

• gives rise to genetically identical offspring known as clones

• the cells in your body divide into two identical cells for growth and to replace worn-out tissues

What are the advantages of asexual reproduction?

• many identical offspring can be produced when conditions are favorable which is faster

• more efficient because only on Parent is involved in the process of reproduction

What are the properties of sexual reproduction?

• involves a male sex cell and a sex cell from two parents

• these two special sex cells (gametes) join together to form a zygote which goes on to develop into a new individual

Which cells are in the gametes of plants in sexual reproduction?

Ovules and the pollen

Which cells are in the gametes of ianimalsn sexual reproduction?

Oval eggs and the sperm

Why is sexual reproduction so important?

The variation it produces is a great advantage in making sure that a species survives. Variation makes it more likely that at least a few of the offspring will have the ability to survive difficult conditions.

Explain when it is useful to have variation in the offspring.

Variation in offspring is important for survival and adaptation. it creates genetic diversity, helping species adjust to changing environments, resist diseases, and avoid extinction with variation, some individuals may develop traits that improve survival and reproduction, driving evolution and making populations more resilient.

What are the causes of variation?

Continuous variation

Gradual transition between two extremes, this features are determined by a number of different genes and are affected by the environment

Discontinuous variation

Little or no environmental impact on the features this features are determined by a single gene lor chromosome)

What do genes control?

The development of characteristics however they may be changed by the environment
