MEIOSIS AND SEXUAL LIFE CYCLES What is heredity The transmission of traits from one generation to the next A gene’s specific location along the length of a chromosome is called the Locus What occurs in asexual reproduction A single individual is the sole parent and passes copies of all its genes to its offspring, What are several mechanisms that can be used to reproduce asexually 1. mitotic cell division in unicellular eukaryotic cells 2. vegetative reproduction ex. Plant cuttings, hydra budding 3. parthenogenesis- females produce offspring from unfertilized egg What are gametes They are haploid reproductive cells that transmit genes across generations. Ex. Sperm and eggs What are somatic cells Any cell other than a gamete and has 46 chromosomes What are autosomes and how many homologous pairs are there Chromosomes other than the x and y chromosomes. 22 homologous pairs What are four characteristics of autosomes 1. same length 2. same centromere position 3. same sequence +/- 4. same genes What is a diploid cell Any cell with two chromosomes set. Humans have a diploid number of 46 What are haploid cells A cell containing only one set of chromosomes. Ex gametes. What is the human haploid number
