Genetics and Heredity: Part 2

An "X" or "Y" shaped bundle of condensed chromatin that contains genes

• histones

• allele

• chromosome

• genotype

Uncondensed genetic material containing DNA and histones; found in the nucleus during interphase

• chromosome

• chromatin

• allele

• gamete

Specific proteins around which DNA is wrapped

• allele

• gene

• histones

• haploid

A section of DNA in a chromosome that codes for a specific trait or enzyme

• allele

• gene

• haploid

• diploid

Half of the functional genotype of an organism; can be paternal or maternal

• gene

• allele

• phenotype

• karyotype

The representation of the alleles for traits possessed by an organism (the code)

• karyotype

• gene

• genotype

• phenotype

The physical description of what is caused by a particular genotype (the trait)

• karyotype

• genotype

• phenotype

• allele

A full map of all of the chromosomes of an organism

• karyotype

• phenotype

• diploid

Word describing a cell that has half of the chromosomes of a complex organism; usually used to describe a gamete

• haploid

Also called sex cells or germ cells, these are haploid cells produced by meiosis that are used in sexual reproduction
