None of the answers are correct Which of the following diseases show pleiotropic A. albinism B. muscular dystrophy C. colorblindness D. sickle cel anemia E. male pattern baldness The gene interaction demonstrated by Labrador retriever coat color, in which the F_2 phenotypic ratio from an F_1 dihybrid cross is 9: 34 is known as A. complementary gene interaction B. recessive epistasis C. dominant epistasis I D. redundancy Environmental conditions that allow conditional lethal to live are known as _____conditions A. permissive B. restrictive When a late blooming pea and an early blooming pea are crossed and an intermediate phenotype occurs, this result would suggest blending A. True B. False The gene interaction demonstrated by sweet pea flower color, in which the F_2 phenotypic ratio from an F_1 dihybrid cross is 9: 7 is known as A. complementary gene interaction B. recessive epistasis C. dominant epistasis I D. redundancy Genes are appear to "travel" together from one generation to the next more often than not exhibit genetic linkage A. True B. False When genes linked, parental combinations outnumber recombinant types are A. True B. False What happens physically during the process of crossing over? A. Two homologous chromatids break and rejoin random sites along the chromosome. B. The genetic information on one chromatid is replaced by copying genetic information from a homozygous chromatid without there being any physical exchange between the chromosomes C. Two homologous chromatids break rejoin at precisely the same site along the chromosome so that there is no loss or gain of material on either product. D. It is not known what occurs during crossing over Genes chained together linkage relationships are known collectively as a linkage group. A. True B. False The closer two genes are on a chromosome the less likely recombination will occur between them. A. True B. False Recombinant offspring inherit the same allele combinations as their parents had. A. True B. False When using chi square analysis and possibly linked genes, your null hypothesis must be that the genes are not linked A. True B. False Crossing-over allows the assortment of linked genes. A. True B. False
Explanation / Answer
Ans13: another name for normal gene is : wild type.
Wild type gene codes for a phenotype that is most prevalent Ina particular population. Mutant gene referers to the altered version of the wild type gene.so option A is correct.
