FLASHCARD QUESTION
Front
Gamete Noun
[gam-eet]
Back
Gamete
A reproductive cell, such as a sperm or egg, that contains half the number of chromosomes (haploid).
Example: This image shows the two types of gametes, or sex cells: the sperm and the ovum (egg), which are essential for sexual reproduction.

FLASHCARD QUESTION
Front
Fertilization Noun
[fur-til-eye-zay-shun]
Back
Fertilization
The process where a male gamete and a female gamete unite to form a new, fertilized cell (zygote).
Example: This diagram shows a sperm cell and an egg cell combining in a process called fertilization to create a new cell called a zygote.
3.
FLASHCARD QUESTION
Front
Zygote Noun
[zy-goat]
Back
Zygote
The new, diploid cell that forms from the fusion of two gametes during fertilization.
Example: This diagram shows that when a sperm cell fertilizes an egg cell, they combine to form a single new cell called a zygote.

FLASHCARD QUESTION
Front
Haploid Noun
[hap-loid]
Back
Haploid
A cell having only one set of chromosomes (1N), such as a gamete.
Example: This image shows that haploid cells, labeled (n), have only one copy of each chromosome, unlike diploid cells which have two copies.
5.
FLASHCARD QUESTION
Front
Diploid Noun
[dip-loid]
Back
Diploid
A cell that contains two sets of chromosomes (2N), one set inherited from each parent.
Example: This image shows that diploid cells (2n) contain two complete sets of chromosomes, with each chromosome having a matching homologous pair.

FLASHCARD QUESTION
Front
Homologous Chromosomes Noun
[huh-mol-uh-gus kroh-muh-sohmz]
Back
Homologous Chromosomes
A pair of chromosomes, one from each parent, that have genes for the same traits in the same order.
Example: This diagram shows a pair of homologous chromosomes, which have the same size and shape. It highlights that they carry genes for the same traits at the same position, called a locus.
7.
FLASHCARD QUESTION
Front
Meiosis Noun
[my-oh-sis]
Back
Meiosis
A type of cell division that reduces the chromosome number by half, producing four unique haploid gametes.
Example: This diagram shows how a single parent cell undergoes two rounds of division (Meiosis I and II) to produce four unique daughter cells (gametes).
