chap15: modes of reproduction

Question 1

what is aesexual reproduction

Answer 1

the process that results in genetically identical offsprings from only one parent

Question 2

what is mitosis and what is it’s importance

Answer 2

mitosis is a type of cell division that results in genetically identical cells
it is important for chromosome number to be maintained, allows aesexual reproduction to occur and damaged tissues to be repaired

Question 3

what are advantages of aesexual reproduction

Answer 3

only one parent is needed, fusion of gametes is not needed
faster than sexual reproduction
beneficial qualities of parent is immediately passed down to offspring since they are genetically identical

Question 4

what are the disadvantages of aesexual reproduction

Answer 4

no genetic variation, species are not well adapted to changes in the environment

Question 5

what is sexual reproduction

Answer 5

the fusion of 2 gametes to form a zygote
produces genetically dissimilar offsprings

Question 6

what is meiosis and why is it important

Answer 6

a type off cell division that produces genetically dissimilar cells that have halved chromosome number
it is importantly to produce haploid gametes and ensure that they’re are genetically dissimilar for greater genetic variation

Question 7

haploid vs diploid

Answer 7

haploid (gamete) is a cell with 1 set of chromosome
diploid (zygote) is c ell with 2 sets of chromosomes (1 male, 1 female)

Question 8

what are the advantages of sexual reproduction

Answer 8

offspring will inherit the most beneficial equalities from both parents
there is genetic variation which allows offsprings to be more adapted to changes in its environment

Question 9

what are the disadvantages of sexual reproduction

Answer 9

2 parents are required, fusion of gametes is needed
method is slower than aesexual reproduction
