Document Summary
Chromosome is composed of dna and associated proteins. Gene segment of dna that contains the sequence for a protein. Chromosome pairs = homologous chromosomes; one maternal one paternal. Similar structure carry genetic information influencing the same traits. Genes can have different forms, called alleles. Individuals only have two alleles at a single locus one from each parent. Alleles in a pair can be identical or different. Offspring receive one allele from the mother and one from the father. Each gamete contains one member of a pair (one from the mother or one from. These pairs are united when gametes fuse. Offspring have full number of chromosomes from mother from father the father) Traits controlled by alleles at 1 genetic locus. Allele a different version of a trait/gene. Locus the gene"s position on the chromosome. Dominant and recessive traits which phenotype will show. Homo/heterozygous homo = two dom. , hetero = one dom.
