24 sie 2013 · Eukaryotic chromosomes are made of DNA and proteins. A gene is a heritable factor that controls a specific characteristic. Alleles are different forms of the same gene that occupy the same locus. A genome is the complete set of genetic material of an organism.
14 cze 2011 · The document discusses key genetics concepts including chromosomes, DNA, genes, alleles, dominant and recessive traits, Punnett squares, sex-linked inheritance, and pedigrees. It provides examples to illustrate genetic inheritance patterns and the use of tools like Punnett squares and pedigrees to predict offspring traits.
5 kwi 2015 · This document provides definitions and explanations of key genetics concepts and terminology. It begins by defining genetics as the science of heredity and the transmission of traits from parents to offspring. It then discusses DNA and genes, chromosomes, alleles, phenotypes, and other basic genetic concepts.
29 lis 2023 · While an allele refers to a variant form of a gene, a gene is a broader term that refers to a unit of heredity in general. A gene is a sequence of DNA that contains the information to produce a specific protein or set of proteins, whereas alleles are the different forms this gene might take.
A gene is a segment of DNA that determines a trait. 5 • Chromosomes come in homologous pairs, thus genes come in pairs. Homologous pairs – matching genes – one from female parent and one from...
Class Notes: Learning Goal: Explain Mendelian genetics using modern cell biology explanations. Use your new understanding to create “new” definitions that explain using mutation, gene products, and pigment. Why are white pea flowers white? Old: They are homozygous for the recessive allele
What makes one cell different from another? DNA = “the life instructions of the cell” Gene = segment of DNA that tells the cell how to make a certain protein. Allele = one of two or more different versions of a gene. Sequence for normal adult hemoglobin: Sequence for mutant hemoglobin: Wild-type Hemoglobin Protein. Mutant Protein.
