Where are they found?What types of cells are Diploid? Where are they found?Two similar chromosomes that you inherit from your parents (one from your mother, one from your father) are called?How many chromosomes does a human inherit from their mother? How many autosomes and how many sex chromosomes?Describe what happens before, during and after DNA replication has taken placeAt what point in the cell cycle does DNA replication occur and why?Four different segments of a DNA molecule are represented below. There is an error in the DNA in which molecule?What could cause a mutation in DNA?Identify the process shown at point Z?What type of RNA molecule carries amino acids to the site of protein synthesisDescribe the structure and function of DNA.Describe the structure and function of RNA.Describe the direction of transfer of genetic information in most living things using the terms, Protein, DNA, mRNA, tRNA.The process of synthesizing mRNA along a DNA template is called…A. the man is not the true father.? B. the man is heterozygous.? C. eye color is sex-linked.?D. both parents are homozygous.?Brown eye color is dominant; blue is recessive. If a brown-eyed man marries a blue-eyed woman and they have a brown-eyed boy and a blue-eyed girl, we can safely conclude…When crossing a homozygous recessive with a heterozygote, what is the chance of getting an offspring with the homozygous recessive phenotype?In rabbits, the allele for long hair (h) is recessive to the allele for short hair (H). When a short-haired female was mated with a long-haired male, the offspring consisted of five short-haired and three long-haired rabbits. The genotypes of the parent rabbits must be:In snapdragons, heterozygotes have pink flowers, whereas homozygotes have red or white flowers. When plants with red flowers are crossed with plants with white flowers, what proportion of the offspring will have pink flowers?Homozygous dominant guinea pigs are white. Homozygous recessive guinea pigs are black. Heterozygous guinea pigs are spotted with both black and white. This is an example of…In 1944 Charlie Chaplin was involved in a legal battle over the paternity of a child born to Joan Berry, a young starlet. The baby was blood type B, the mother A, and Chaplin O. From what you know about the inheritance of blood types, could Chaplin have been the father of the child? (At the time of the trial, blood group evidence was not admissible in California courts. Charlie Chaplin was declared responsible for the child's support.)During one of Mendel’s experiments, ?Generation I, true-breeding, long-stemmed pea plants were crossed with true-breeding, short-stemmed pea plants. ?In Generation II all the plants were long-stemmed. When the Generation II plants were cross-pollinated among themselves, the percentage of short-stemmed pea plants in Generation III was likely to be…The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth peas is (S) and the trait for wrinkled is (s). Two plants are crossed yielding an F1 generation with 612 tall plants with smooth peas and 188 short plants with wrinkled peas. What is most likely the genotype of the parent generation?The gene for Rh+ blood is dominant over the gene for Rh- blood. An Rh- woman whose mother was Rh- marries a Rh+ man, both of whose parents were Rh+. What percentage of their children will be expected to be Rh+?Hemophilia is a genetic disease that has plagued the royal houses of Europe since the time of England's Queen Victoria, who was a carrier. Her granddaughter Alexandra married Nicholas II, the last Tsar of Imperial Russia. Alexandra was a carrier of the gene for hemophilia; Nicholas was normal. Their son, the Tsarevich Alexis, was afflicted with the disease. Alexis and his four sisters are all thought to have been killed at the outbreak of the Revolution of 1917. Who is likely a carrier?Theoretically, if a carrier hemophiliac married a normal male, what percentage of their male offspring would be expected to be carriers?A dihybrid cross tests for what rules or laws?The idea that for any particular trait, the pair of alleles of each parent separate and only one allele from each parent passes to an offspring is Mendel's principle of:Consider the following pedigree. The most likely mode of inheritance is:Autosomal recessive, Autosomal dominant, X-linked recessive, or X-linked dominantWidow’s peak is an autosomal dominant condition. The pedigree given shows a family in which shaded individuals have the condition. Explain the pedigree. ................
