- You have a true-breeding strain of miniature-winged fruit flies, where this wing trait is recessive to the normal long wings. How would you show whether the miniature wing trait is sex-linked or autosomal?Consider the pedigree of a family with a disorder of unknown inheritance. Note that individual 11 is known to have no affected alleles. Superscript a indicates the affected allele for sex-linked traits. (image attached) What are the possible genotypes of individual 1? XAXA aa Aa AA XAXa XaXaGiven the pedigree below: Is the trait dominant or recessive? What are the most likely genotypes of individuals I-1 and I-2? What is the probability that individual II-2 is a carrier?
- Consider the pedigree below for a recessive autosomal trait caused by allele t. The dominant wild-type allele is represented by T. What is the genotype of individual 4 in generation II?This chart shows different patterns of inheritance in four pedigrees. Assume that individuals marrying into the family are homozygous for the wild-type allele. Which pedigree shows an autosomal dominant pattern of inheritance? a. III b. IV c. II d. IConsider the two traits: Blood Type B (Parents and Child with Blood Type B, Grandparents unknown) and Earlobe (Father - Hanging; Mother - Attached; Son - Hanging; Grandparents - unkonwn). From these, create a 3-generation pedigree chart include labels for the alleles.What is a possible analysis regarding the mode of inheritance of the observed traits?
- Assume that attached earlobes is an autosomal recessive trait with 47% penetrance. If one parent is heterozygous (Aa) and the other homozygous recessive (aa) for the attached earlobe gene, what is the probability that their first child will have attached earlobes? Show calculations please! a. 50%b. 11.75%c. 25%d. 23.5%e. 74%For the pedigree shown here, the disorder is caused by a recessive (g) autosomal allele. Label each of the following individuals with the correct genotypa. Generation I, number 2 b. Generation II, number 1 c. Generation II, number 2 d. Generation III, number 3Consider the two traits: Blood Type B (Parents and Child with Blood Type B, Grandparents unknown) and Hanging Earlobe (Parents and Child with Blood Type B, Grandparents unknown). From this, create a 3-generation pedigree chart (starting from grandparents' generation).What is a possible analysis regarding the mode of inheritance of the observed traits?
- a) Given the phenotypes below, which genotypes can you determine with certainty? Justify your answer. MOM A- CHILD AB+ DAD 1 AB+ DAD 2 B+ DAD 3 O- b) Can you eliminate any of the possible fathers? Explain why or why not. c) Is it possible to say with certainty which one (of the 3) is the father? Explain your answer.Gene A has three possible alleles (A1, A2, A3), gebe B has four possible alleles ( B1 - B4), and gene C has five possible alleles (C1 - C5). How many diploid genotypes are possible considering these three genes?Consider the pedigree below for a recessive autosomal trait caused by allele t. The dominant wild-type allele is represented by T. What is the genotype of individual 5 in generation II? A. TT or Tt B. tt C. Tt D. Tt or tt E. TT
