Can someone show me why this is correct? I will like to see the possible genotypes and
Step by step
Solved in 4 steps
- In this pedigree chart, what is the genotype of individual III-1? (It's circled in blue.)what is the probability that if the couple has three children, none of them will be affected by the syndrome. refer to the attached picture and show solution. is it 107/144? can you verify my answer. please refer to the picture below.Are my answers correct for this pedigree?
- 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 com, male sterility is controlled by maternal cytoplasmic elements. However, the presence of a nuclear fertility restorer gene (F_) restores fertility to male sterile lines. Using the following cardboard chips, simulate the crosses indicated below. Present your cross to your instructor for checking. After being checked, draw your simulated crosses in the spacesprovided below. Give the genotypes and phenotypes of the offspring in each cross, and properly label the nucleus and the cytoplasm of each individual in the crosses.Big white circular chips Male sterile cytoplasmBig peach circular chips Male fertile cytoplasmSmall peach circular chips FF nucleusSmall half-white-half-peach circular chips Ff nucleusSmall white circular chips ff nucleus a. male sterile female x FF maleExplain your results. b. male sterile female x Ff maleExplain your results.Does that mean if someone is a carrier the genotype will be Fh/fh? Because Fh is the diseased allele and fh is the wildtype or how will is it going to be. I am not sure how to answer it.
