asexual reproduciton
creates offspring that are genetically identical to each other and to the parent cell(clones)
what is only required during asexual reproduction?
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?
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
more than two sets of chromosomes, common in plants
meiosis reduces
chromosome number, producing up to 4 haploid cells from one diploid cell
