Bald eagle population Since DDT was banned and the Endangered Species Act was passed in 1973, the number of bald eagles in the United States has increased dramatically (see the figure). In the lower 48 slates, the number of breeding pairs of bald eagles increased at a nearly linear rate from 1875 pairs in 1986 to 6471 pairs in the year 2000. a. Find a linear? ?function ? (?t) that models the number of breeding pairs from 1986 t?o 2000 (0 ? ?t ? 14). b. Using the function in part (a), approximately how many breeding pairs were in the lower 48 slates in 1995? ?

Wednesday, January 25, 2017 Genetics and Animal Breeding Genetics: a discipline of biology that studies the heredity and variation in living organisms - All of the genetic information of an animal is found in the genome - The genome is the map of all of the genes in the animal - Genotype is the genetic make up of an organism - Alleles are a form of a specific gene located in a particular position on the chromosome - Expression is the manifestation of a characteristic that is specified by a gene - Expression of the genes can determine the worth of an animal - Applied genetics in animals is usually referred to as animal breeding INTRO TO GENETICS -Chromosomes are large molecules containing the genes of a living thing -Chromosomes are replicated during cell division -Chromosom
