|
asexual reproduciton
|
creates offspring that are genetically identical to each other and to the parent cell(clones)
|
|
|
what is only required during asexual reproduction?
|
mitosis
|
|
|
compared to sexual reproduction, asexual reproduction is typically?
|
rapid and efficient
|
|
|
sexual reproduction
|
occurs when specialized sex cells called gametes fuse to form a single cell called a zygote
|
|
|
usually gametes that fuse are produced by?
|
different individuals, but mey be produced by the same individual
|
|
|
in plant and animal cells, the gametes are called
|
egg and sperm
|
|
|
offspring of parents are not?
|
genetically identical
|
|
|
sexual reproduciton must contain a mechanism to?
|
half the number of chromosomes at some point
|
|
|
halving the chromosome number is accomplished through?
|
meiosis
|
|
|
diploid cells give rise to what during meiosis?
|
haploid cells
|
|
|
the somatic cells of animals and higher plants are?
|
diploid cells
|
|
|
each chromosome in a diploid cell has?
|
a partner chromosome
|
|
|
the partner chromosome to each chromosome is called?
|
homologous chromosomes
|
|
|
one member of each pair comes from?
|
one from the mother and one from the father
|
|
|
humans have how many chromosomes?
|
46, 23 pairs
|
|
|
homologous pairs contian similar but not identical
|
genetic information
|
|
|
sex chromosomes aren't strictly
|
homologous but they act as if they are during meiosis
|
|
|
a diploid cell has two complete sets of
|
chromosomes, while a haploid cell has one
|
|
|
polyploid
|
more than two sets of chromosomes, common in plants
|
|
|
meiosis reduces
|
chromosome number, producing up to 4 haploid cells from one diploid cell
|
