Reproduction And Development Flashcards
species
group of organisms that can share certain characteristics and can mate with one another, producing fertile offspring
gamete
sex cell
mitosis
the process that divides the cell’s nucleus into two, each of the complete set of genetic material from the parent cell
meiosis
process that results in the production of sex cells
fertilization
process that combines a sperm cell and an egg cell
zygote
fertilized egg
recombination
additional mixing of genetic material from a sperm and egg which results in a unique combination of genes
differentiation
process that transforms developing cells into specialized cells with different structures and functions
embryo
organism in the early stages of development
gene expression
results of activated genes
ovary
the organ of the human female reproductive system that produces an egg cell
progesterone
a hormone associated with sexual development and the reproductive system
estrogen
a hormone (produced by the ovaries) that controls female sexual development and the reproductive process
uterus
