Bsc1005 BIOLOGY MODULE 3 CHAPTER 1-CHAPTER 9 LATEST 2024 (VERIFIED ANSWERS) __________ contain multiple genes which have different versions called alleles - ANSchromosomes a __________ does not carry a Y chromosome, which can be identified in a karyotype as a much smaller chromosome in the pair of sex chromosomes. In this karyotype, all chromosome pairs are relatively the same in size. - ANS-female a __________is a locus on a chromosome that usually codes for a protein. There are two alleles for each __________, one on each chromosome homologue. - ANS-gene a change in a single gene [does or does not] affect chromosome number or size, which are what a karyotype analysis can detect. - ANS-does not a diagram similar to a family tree that illustrates genetic relationships is called a _________. These diagrams can be analyzed to investigate the inheritance patterns of genetic disorders. A genetic disorder that appears in an offspring of a family that has no history of the disorder is likely a _________condition. Such an outcome suggests that _________ parent(s) acted as a carrier for the disorder. - ANS-pedigree, recessive, both a man is homozygous for an autosomal recessive genetic condition. His mate does not possess the allele. What are the chances that their first son would express the condition? a. 100% b. 25% c. 50% d. 0% - ANS-d a man possesses an allele for a recessive X-linked genetic condition, and his wife does not possess the allele. What are the odds that the couple's son will express the condition? a. 100% b. 25% c. 50% d. 0% - ANS-d. 0% a man possesses one allele for a dominant genetic condition carried on chromosome 12, and one for a recessive genetic condition carried on chromosome 20. Which of the following statements is true regarding the inheritance of these two trai
