Please answer all of them, they are all connected. PEDIGREE ANALYSIS and SYMBOLOGY: Examine the pedigree which has X linked Dominant inheritance of disorder. Use letter X* (asterisk denotes disorder) as genotype of the individuals which can be XX, XY, X*X*, X*X and X*Y. a. What is the genotype of IV-6? b. What is the genotype of III-6? c. What is the genotype of II-3? d. What is the genotype of III-8? e. If couple I-1 and I-2 will have a son, what is the probability of having the disorder? f. If couple III-8 and III-9 will have another child, what is the probability of having the disorder? g. Theoretically, if individual IV-3 and individual IV-5 will marry and will have a child, what is the probability of having a child without the X-linked disorder?
Show the complete solution including the Punnett Sq. Lina has dimples, freckles, and a widow’s peak. She is a heterozygous for all of the three traits. David, her husband also has freckles and dimples but has a continuous hairline. As freckle is known to be dominant over none, dimples are dominant over no dimples, and widow’s peak is dominant over continuous hairline, identify the Probability that their child will have three recessiveness: no freckle, no dimples, and has widow’s peak; and Probability that their child will have the same phenotype as Lina (with freckles, dimples, and widow’s peak). Legend: Ff – freckles Dd – dimples Ww – widow’s peak
What is the predicted phenotypic ratio for the offspring of the following cross? Allele phenotypes: R = red, r = white, T = thin leaf, t = broad leaf Cross: RR; Tt x Rr; tt Red with thin leaves ___________ Red with broad leaves ___________ White with thin leaves ___________ White with broad leaves __________ PLEASE show work and give an explanation... Thank you!
A phenotypic ratio of 6:6:4 is possible between a male who is heterozygous free earlobes and heterozygous freckles, and a female who is homozygous free earlobes and heterozygous. The genotype of the female is written this way Eeff. Key: E = free earlobes e = attached earlobes F = freckles f = no freckles O If both statements are FALSE If both statements are TRUE O If the first statement is FALSE and the second statement is TRUE O If the first statement is TRUE and the second statement is FALSE
I just want an explanation of what is in bold please. Lab Introduction: A dihybrid cross is a cross between individuals that involves two pairs of contrasting traits. To Predict the results of a dihybrid, cross all possible combinations of the four alleles from each parent must be considered. You will examine a dihybrid cross involving both color and texture. Purple (P), is dominate to yellow (p), and smooth texture (S) is dominant to wrinkled (s). Both parent plants are heterozygous for both traits. Review genetics and the use of Punnett squares in a biology text before doing this experiment.MATERIALS: Assume you have ear of Corn. You need a heterozygous X heterozygous 9:3:3:1, purple/yellow, starchy/sweet. PROCEDURE: From above please write out: The crop The parental (P) cross phenotype, genotype, gametes The F1 progeny Genotype and Phenotype Cross between two F1 Selfed testcross The F1 gametes The expected F2 results, genotype, phenotype, genotypic ratio, phenotypic ratio. 1.…
In a species of flowers, blue petals are dominant over purple petals, and a long stem is dominant over a short one. Cross a flower that is heterozygous for both traits with a flower that is homozygous recessive for petal color and homozygous dominant for stem length. Report the genotype and phenotype. *Write your answers in ratio non-reduced form (Example 16:8) Genotype Phenotype
type P = n! (p)* (q)"* х! (n - х)! Practice Problem: You cross a true-breeding pea plant with red flowers to a true-breeding pea plant with white flowers. All of your offspring have red flowers. Which gene is dominant? Why? What is the genotype of your offspring? You then cross the offspring to each other. What ratio do you expect? Why? You count 1000 plants and look at their flowers. Your results are as follows: 740 red 260 white Does this follow a simple Mendelian inheritance pattern? Why or why not? DADT 2 MEA SUDI ND D LUT IONS
Purple flowers are dominant to white flowers. Identify the phenotypefor the following genotype Ff, FF, ff and determine if the genotype is heterozygous or homozygous. * For each row, you should select two columns.

Identify the phenotype for the following genotype BB, Bb, bb and determine if the genotype is heterozygous or homozygous. * 口ロ口

SEATWORK Symbols (for pea plant traits): • T: Tall t: short Analyze the following problems. Determine the possible genotypes, genotypic ratio, phenotypes, and phenotypic ratio from the genetic cross. Show your solution through a Punnett square. Use the symbols provided. • R: Round seeds r: wrinkled seeds • Y: Yellow seeds y: green seeds • P: Purple flower p: white flower 1) Cross a homozygous dominant tall and homozygous round seed pea plant with a heterozygous tall and heterozygous round seed pea plant. 2) Cross a pea plant that is heterozygous for purple flowers and homozygous dominant for yellow seeds with a pea plant that is heterozygous for purple flowers and homozygous recessive for green seeds. 3) Cross a pea plant that is short and has green seeds with a pea plant that is heterozygous tall and has heterozygous yellow seeds.
The next four questions are all related to this problem: Polydactyly (PD) is an autosomal dominant trait (polydactyly - P; wildtype - p). Cystic fibrosis (CF) is an autosomal recessive trait (cystic fibrosis - f; wildtype - F). A PD woman, otherwise normal in phenotype, marries a healthy normal man. Their 4 children are: 1) normal, 2) PD, 3) CF, 4) CF + PD. You will walk through a series of steps to answer this question: What is the probability that their 5th child will have at least one of these conditions? Here is the first step: 1. What is the cross? (Hint: You can use the 4 existing children to determine the genotypes of the parents.)

Solve the given Problems: (Put the correct symbolic cross and correct answer to the given questions.) A. The man is heterozygous type B (BO) and the partner is homozygous type A (AA). Do the cross to show how it happens and answer the following: What are the different blood types and the corresponding genotypes of their kids? What is the chance or the probability to have a blood type B child? How about the chance to have a type AB child? If the couple plans to have 3 kids, how many combinations of blood types will be true for their kids?
pt pt PT PPTt purple tall PpTt purple tall Pt Pptt purple white Pptt purple white Using any two plants resulting from your test cross (even two of the same genotypes if you would prefer), perform a second cross. Provide a Punnett square demonstrating this dihybrid cross.What are the ratios for each genotype in the resulting offspring? What are the ratios for each phenotype? Your answer should clearly indicate the genotype and phenotype each portion of the ratio is referring to
