- In a paternity case a single mother claimed that a certain man was the father of her baby. The man denied it claiming that her current boyfriend was the father. The court ordered a blood test (cheaper than dna testing) to see if he could be ruled out as the father. The mother is type O and the baby was type O the man was type AB.

Explain your reasoning and show the cross.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?

Cross two of the offspring from the above cross (sorry about the incest). What are the genotypes and phenotypes or their offspring? b. Cross a heterozygous freckled man with a nonfreckled woman. What are the genotypes and phenotypes of their offspring?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.…Can someone show me why this is correct? I will like to see the possible genotypes and phenotypes together that proves the answer.
- Sleepy the Emoji was always self-conscious of her closed eyes and she fell in love with a handsome open-eyed emoji dude, but she wasn't sure if he was homozygous or heterozygous for his open eyes. Their First child had open eyes but the second child had closed eyes. What genotype did emoji dude have? Create two Punnett squares and explain how you know his genotype using evidence from your squaresMy Question is what is the probability their first child will have hemophilia and drawn pedigrees for family members with genotypes. My explantion so far: A man has both X and Y chromosomes as sex chromosomes in his body. Here, though the brother of the man is hemophiliac, a man can’t be a carrier of hemophilia. So, it can be said that his chromosome is “XnY”.Here, the “n” stands for “normal”.Though the paternal uncle is hemophiliac, a man cannot be a carrier of hemophilia, his niece will not be a career. So it can be said that the woman is also not a carrier and has the “XnX” chromosome.So, as the mother is not a carrier, their first child does not have a chance of having hemophilia. This can be determined as it is known that there is no hidden carrier of hemophilia in the family.An organism with genotype of Tt is what phenotype
