The phases of meiosis that cause the most variation in the four resulting daughter cells are
prophase I and anaphase I
How does the sexual life cycle increase the genetic variation in a species
by producing gametes with different combinations of parental chromosomes, by allowing the combination of chromosomes from two different individuals, by allowing recombination of alleles on a chromosome.
referring to a plant sexual life cycle, choose the pair of terms in which the first term describes the process that leads directly to the formation of gametes, while the second term describes restoration of the diploid chromosome number from the haploid state
gametophyte mitosis; fertilization
which of the following is the term for a human cell that contains 22 pairs autosomes and two X chromosomes
female somatic cell
all of the following are functions of meiosis in plants except
independent assortment of chromosomes
a cell with diploid number 4, chromosomes A, B, C, D. If meiosis occurred with the formation of homologous pairs AC and BD, and the chromosomes were then distributed randomly between the resulting cells, how many gametes could be formed.
4 (AB, AD, BC, and CD)
eukaryotic sexual life cycles show tremendous variation. of the following elements, which do all sexual life cycles have in common.
meiosis, fertilization, gametes
what is a karyotype
a method of organizing the homologous chromosomes of a cell in relation to their number, size, and type
tetrads of chromosomes are aligned at the center of the cell; independent assortment follows
in the alternation of generations found in plants
the gametophyte generation produces gametes by mitosis
