Reproduction

Question 1

what is sexual reproduction? (technical)

Answer 1

• Where genetic information from two organisms is combined to produce off spring that are genetically different to either parent

Question 2

In sexual reproduction , what do the mother and father produce?

Answer 2

• Gametes by meiosis
  Each gametes contains 23 chromosomes - half the number of chromosomes in a normal cell
  The egg and sperm cell then fuse together to form a cell with the full number of chromosomes.

Question 3

Sexual reproduction definition

Answer 3

• Involves the fusion of male and female gametes. Because there are two parents = the offspring contain a mixture of their parents genes
• This is why offspring inherit features from both parents - receives a mixture of chromosomes from mom and dad

Question 4

What does the mixture of genetic information produce?

Answer 4

• Variation in the offspring
  Flowering plants can reproduce in this way too they have egg cells but the sperm is known as pollen

Question 5

Define asexual reproduction

Answer 5

There’s one parent who is genetically identical to offspring. There’s no fusion of gametes, no mixing of chromosomes and no genetic variation between parent and offspring.
The offspring is genetically identical; to the parent = clones

Question 6

When does asexual reproduction occur??

Answer 6

• mitosis - ordinary cell makes a new cell by dividing in 2

Question 7

examples of things that asexually reproduce

Answer 7

• Bacteria, some plants and some animals
