Biology Chapter 11B Matching Test #2

somatic cells

body cells

homologous chromosomes (1)

they have the same morphology

homologous chromosomes (2)

they carry information regarding the same traits

gametes

haploid

gametes (2)

combine to form the zygote

zygote

the diploid cell that results from the union of gametes

zygote (2)

carries the combined genetic material of both gametes (i.e. parents)

zygote (3)

divides by mitosis, forming the diploid somatic cells of the new multicellular organism

interphase

same as prior to mitosis

interphase (2)

the DNA replicates

interphase (3)

DNA is in chromatin form

crossing over

the physical overlapping of sections of chromatids as the homologous chromosomes form tetrads during prophase I of meiosis

crossing over (2)

causes pieces of the chromatids to exchange places

sperm production

the cytoplasm divides evenly in both Telophase I and Telophase II

sperm production (2)

results in four uniform, functional cells

egg production

the cytoplasm divides unevenly in both Telophase I and Telophase II

egg production (2)

results in one functional (quite large, lots of cytoplasm)
