lab quiz 5 Flashcards
genetics
the study of the inheritance
chromosomes
are traits passed through
DNA deoxyribonucleic acids
chromosomes are composed of DNA and proteins
genes
are sections of DNA that encode traits
homologous pairs of chromosomes
carry the same genes, but can carry different versions of each gene
alleles
different versions of a gene
phenotypes
physical traits
genotypes
genetics traits
dominant
expressed when there is one allele present
recessive
only expressed when two of the same alleles are present
interphase
chromosomal are replicated
centromere
where the two copies of chromosome are held together
independent assortment
each chromosome is paired with its homologue, and members of a pair sit on opposite sides of an imagery line that runs through the center of the cell, called the equator
anaphase I
occurs when the homologous pairs separate and move toward opposite sides of the cell
telophase I
when the pairs are at separate side of the cell
