Exercises Jaa 20/1. Right or wrong? Kirjaudu sisään lähettääksesi tämän lomakkeen Are the following statements correct or incorrect? 1. Allelesa) Each individual has more than two different alleles for each gene. correct incorrect b) The allele is a gene form. correct incorrect c) Alleles are inherited from both parents. correct incorrect d) Example: The formation of an earlobe is influenced by a gene. It has two gene forms, or alleles: One produces an attached earlobe, the other a free earlobe. correct incorrect 2. Dominant allelesa) The gene form of the dominant allele masks the effect of the recessive allele gene form. correct incorrect b) The gene form of the recessive allele is never visible. correct incorrect 3. Characteristicsa) All the characteristics of an individual are inherited. correct incorrect b) The living environment has no effect on an individual's characteristics. correct incorrect 4. Proteinsa) Proteins control the functions of genes. correct incorrect b) Genes control the production of proteins. correct incorrect 5. Mutationsa) Mutations are always harmful. correct incorrect b) In a chromosome mutation, one whole chromosome has been duplicated. correct incorrect 6. Hereditary diseasesa) More than one defective gene is required for an outbreak of a hereditary disease. correct incorrect b) The outbreak of hereditary diseases cannot be influenced with individual actions. correct incorrect Kirjaudu sisään lähettääksesi tämän lomakkeen 20/2. Children Kirjaudu sisään lähettääksesi tämän lomakkeen Large-eyedness is denoted by the letter E (a capital letter indicates a dominant feature). Small-eyedness is marked with the letter e. CASE 1: The father has the alleles EE, whereas the mother has the alleles ee. The children are large-eyed (Ee). small-eyed (ee) . small-eyed (eE). CASE 2: The father is Ee and the mother is Ee. The father is large-eyed. small-eyed The mother is large-eyed small-eyed It is probably that over half of the children from these parents are large-eyed. small-eyed. The children of these parents can include no large-eyed individuals. can include no small-eyed individuals can include both large-eyed and small-eyed individuals.
