Biology Chapter 8 Crossword

material that composes the chromosomes; consists of DNA, RNA, and protein
a structure consisting of DNA and supporting proteins, usually found in a cell’s nucleus
a segment of DNA that codes for a specific protein, resulting in a particular trait
one of two identical halves of a chromosome formed prior to cell division
the attachment point of the two chromatids in a chromosome
chromosomes that determine whether an organisms is male or female
a chromosome other than a sex chromosome
referring to one of a pair of chromosomes that carry the same genes in the same order on each chromosome
having two complete sets of chromosomes
having only a single set of chromosomes
the series of events, including duplication of DNA, leading to the division of a cell into two daughter cells
the period of the cell cycle in between cell divisional the time of regular growth and activity
the phase of the cell cycle in which a cell’s duplicated DNA is divided into two identical sets
the process during cell division in which the cytoplasm of a cell is divided between two new daughter cells
the passing of traits from one generation to another
a characteristic that is expressed even in the presence of a recessive allele of the gene that codes for that characteristic
a characteristic that is expressed only in the absence of a dominant allele of the gene that codes for that characteristic
one pair of genes that have the same position on homologous chromosomes and code for the same trait, though each may code for a different form of the trait
describes the condition of having the same two alleles for a gene at the same position on homologous chromosomes
the genetic makeup of an individual organism, especially regarding its particular combination of alleles for a specific trait
the physical expression of a trait in an organism
a diagram that is used to visualize genetic crosses
a genetic cross that tests only one set of alleles
a genetic cross that tests two sets of alleles
a heredity chart that tracks the expression of a trait through several generations
a type of inheritance in which different alleles of a gene are neither dominant nor recessive and are expressed simultaneously, resulting in a blended, usually intermediate phenotype
a type of inheritance in which different alleles of a gene are expressed simultaneously, producing a phenotype that exhibits contributions from both alleles
a condition in which more than two alleles for a gene are possible
a type of inheritance in which a trait is determined by more than one gene
traits coded for by a gene located on a sex chromosome
a heterozygous organism that expresses the normal form of a trait but carries the recessive gene for an undesirable form of the trait and can pass it on to its offspring
