Solved in 2 steps
- I don't really understand how to solve this question. For part a, I think my approach would be to find the genotypes of the parents first, and find the genotype of the F1. For part B, I would like to get some clarifications on the difference between linked genes with no crossing over vs. unlinked genes when approaching Punnett square type questions. Thank you also answer part a and bWhat makes the red? What is this testing used for?Southern Blotting & Detection of sickle cell disease: Please interrupt the following results and draw a Punnett square, and answer the questions. •Discuss figures (gel figure and Punnett square) one by one. •You must provide discussion for each lane of the gel, how you make out normal, carrier, disease (allelic patterns- why so?), control IMPORTANT POINTS TO REMEMBER: •Homozygous (one band)- the size of the band (lower or higher in the gel) determines if normal (both alleles cut by MSt II, hence band lower) or diseased (both alleles uncut and hence at the higher position in gel) •Heterozygous (two bands in the same lane) denotes a carrier (lower band from normal allele which is cut by RE & upper sickle cell allele band is uncut)
- The e-gram (graph to the right of allelic ladder image) and above is from a woman. She has variations 14 and 15 at STR D3S1358. If she has children with a man who has variations 12 and 19 at the same STR, what are the possible combinations of variations that their children would have?All questions a) Name the genetic disorder for individuals A and B. b) Give three characteristics of individual B. c) What is the gender of individual A?Physical maps are constructed by using a chromosome walking technique.a) Trueb) False
- Could someone please help me with this grade 11 bio dihybrid cross problem in detail and how to solve this question, using a strategy? Assume that curly hair (C) is dominant to straight hair. Albinism (P ) is recessive to normal skin pigmentation. A woman who is heterozygous for curly hair and albinism has a child. The father is homozygous dominant for curly hair and has albinism. (a) Determine the possible phenotypes for their child. (double-crossing, Puneet square)(b) Calculate the four different probabilities of a child beingboth a male and of each phenotype.(c) What is the probability that the child will expressalbinism and have curly hair like his father?Is the heritability of COVID-19 susceptibility is close to 1? Based on your knowledge, what is the potential role of the environment in determining susceptibility to COVID-19?The forked line and probability methods make use of what probability rule? test cross product rule monohybrid rule sum rule

Well-balanced heterozygote peaks. C. Sharply pointed peaks with even spectral distribution D. Well-defined smooth peaks with a bell-shaped distribution.QUESTION 3 If parents differ in only a single characteristic during a test cross, it is a ________ cross. a. dihybrid b. monohybrid c. trihybrid
