Gamete - ANSWER sex cell
Zygote - ANSWER fertilized egg
Heterozygous - ANSWER two different alleles
Recessive - ANSWER the allele that is only expressed if homozygous
Dominant - ANSWER the allele that is always expressed if present
Homozygous - ANSWER Both alleles the same
DNA - ANSWER a long molecule that holds all of the genetic information of an
organism
Adenine - ANSWER The base that pairs with Thymine in DNA
Allele - ANSWER one of a number of different forms of a gene
Amino Acid - ANSWER basic building blocks of protein - there are 20 different kinds.
1
, Anther - ANSWER Found in plant flowers, carries pollen - the male gamete of plants
asexual reproduction - ANSWER reproduction that does not involve the union of
gametes and in which a single parent produces offspring that are genetically identical to the
parent
Autosomes - ANSWER Any chromosome that is not a sex chromosome
base - ANSWER 1 of 4 chemicals that make up the rungs of the DNA ladder.
base pair - ANSWER two nucleotides on complementary strands of DNA that form a
pair, linked by hydrogen bonds; the pattern of pairing is adenine (A) with thymine (T) and
cytosine (C) with guanine (G)
biodiversity - ANSWER Variation of a species within an ecosystem
cell - ANSWER basic unit of life
cell division - ANSWER the process in reproduction and growth by which a cell divides
to form daughter cells
chromosome - ANSWER threadlike structure within the nucleus containing the genetic
information that is passed from one generation of cells to the next
cloning - ANSWER A process that produces identical genetic individuals
codon - ANSWER a specific sequence of three adjacent bases on a strand of DNA or
RNA that provides genetic code information for a particular amino acid
