Transcript
Monday 17th October COPY LO: Understand how genetic crosses are represented and how a single gene is inherited. Starter Read through table on Page 115 of textbook BATS • predict the results of monohybrid crosses involving dominant, recessive and co-dominant alleles VERY IMPORTANT - always abide by these rules - DO NOT TAKE SHORT CUTS WHAT DOES MONOHYBRID MEAN? MONOHYBRID means the inheritance of a single gene. What is a pure bred organism? It is one that are homozygous for a character They have been bred for many generations and are constant for that particular gene When organisms are crossed - the offspring are known as the first filial, or F1 generation. If two of the F1 generation are bred/ crossed, the offspring is known as the second filial or F2 generation In pea plants, the allele for tall stems is dominant to the allele for short stems. If two tall-stemmed plants (both heterozygous) are crossed, what percentage of the offspring will be short-stemmed plants? Parental phenotype Parental genotype Parental gametes Offspring genotype Offspring phenotype 1. Answer Q 1-2 on Page 116 Do Application on Page 116 117 Work for Thursday and Holiday Homework 1. Revise - meiosis - topic 8.4 in AS Biology 2. Worksheet - do Q 1-4 2. Read Pages 118 - 120 of textbook then answer all summary questions and do application on page 120 3.
