LIFESCI 4 Chapter Notes - Chapter 13: Karyotype, Somatic Cell, Metaphase
Document Summary
13. 1: offspring acquire genes from parents by inheriting chromosomes. A distinct unit of hereditary information consisting of a specific nucleotide sequence in. Words to pictures = letters (from dna) to features. A gamete is a haploid cell, such as an egg or sperm. Gametes unite during sexual reproduction to produce a diploid zygote. A gene"s specific location along the length of a chromosome is called the gene"s locus. A single individual is the sole parent and passes copies of all its genes to its offspring in asexual reproduction. Involves one parent and that produces genetically identical offspring by the division of a single cell or the entire organism into two or more parts. A clone is a group of genetically identical individuals; these are produced by reproducing asexually. In sexual reproduction, two parents give rise to offspring that have unique combinations of genes inherited from the two parents. 13. 2: fertilization and meiosis alternate in sexual life cycles.
