Chromosomal Genetics Biology Genetics & Inheritance Chromosomal Genetics Questions What are four types of chromosomal mutations? What is the cause of cleft lips and palates? Describe what happens to chromosomes during single and double crossovers. Would we expect to see these happen in gamete (sperm and egg) formation or in body cells? What chromosome does autism occur on? In genetics, what is a trisomy? What are XX and XY chromosomes? What is a sexlinked trait? What chromosome is color blindness attributed to? What is the general term for a condition where the chromosome number is not a multiple of a complete set? What is genetically similar and different about these structures that have been separated to opposite poles of the cell during anaphase I? The body cells of a hamster have 44 chromosomes. How many chromosomes would the gametes of a hamster have? Chromosomes usually appear in pairs. If there are three chromosomes where there should be two, what kind of mutation is this? If a recessive genetic disease occurs much more frequently in men than women, which chromosome should be studied as a possible source of the disease? What results from crossing experiments would suggest 2 loci are on the same chromosome? If a man has a recessive sexlinked disorder, he has a 0% chance of passing it onto his son. Why? If an autosome is present in only one copy at conception, that individual will not develop to term. Yet human males have only one copy of the X chromosome and they do develop normally. Why is there a difference? What disorders are caused from too many or too few sexchromosomes? How do autosomal chromosomes differ from sex chromosomes? What happens to characteristics found in one generation of a species as it reproduces and has offspring? Question #5844c Why do we abbreviate trisomy as n + 1? Question #674c2 Genetic material DNA is contained in our chromosomes. What is the most important role of these chromosomes? Are the sex chromosomes present only in sex cells or in the somatic cells as well? How many pairs of chromosomes are present in the somatic cells? Are the last pair of chromosomes present in the reproductive cells only? Why do we need 2 sets of a single chromosome? Why does it exist two types of chromatin? Question #822fa Question #8dd39 Question #58371 What is polyploidy? Pair of genes(allele) are present on only one chromosome or on homologous chromosomes? Are linked genes the ones that are linked with genes on the same chromosome or with genes on the homologous chromosome? A tetra-hybrid plant produces fruits of 1 kg while minimum weight is 400 g. What will be the maximum weight of a fruit ? (1) 600 g (2) 1600 g (3) 1200 g (4) 1800 g A sperm cell of an alligator has 16 chromosomes.what is the total number of chromosomes normally present in a stomach cell of this alligator?
