Introduction:
Genotype is the genetic constitution of an organism that influences its physical features that are collectively termed as the phenotype of an organism. Genotype and phenotype are related to each other in a way that the latter is influenced by the previous one. Alleles are the different copies of the same gene.

Describe the following (50 words minimum per concept): chromosomes, genes, alleles and traits and explain how they are related.
If a man with dark skin whose genotype is AaBB reproduces with a woman who has light skin (aaBb), what are the possible skin colors that their children will have? Develop a Punnett square and list the possible genotypes & phenotypes. For your convenience, a table is presented below that shows several possible genotypes & phenotypes:
Genotypes Phenotypes
AABB Very dark skin
AABb or AaBB Dark skin
AaBb, AAbb, or aaBB Medium brown skin
Aabb or aaBb Light skin
aabb Very light skin

- Please find an Image/Graphic to represent sickle cell disease: Use at least two different images to help the audience understand the cause and/or inheritance pattern of the disorder you chose. Include a brief 1-2 sentence caption below each image that gives a description of the image and explains its relevance to your chosen disorder. The two images should NOT convey the same exact information. Ideas of images to use include: karyotypes, pedigrees, DNA sequences, etc. Please note: the images should be specific to your chosen disorder. The 2 required images must be related to cause and/or inheritance pattern. Images of an individual with the disorder will not count toward your 2 required images as they do not contribute to the audience's understanding of cause and/or inheritance pattern.arrow_forwardHemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "N" for normal and "n" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (NN or Nn or nn) but a man will have only one allele (N or n). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a.What are the genotypes of the parents? b.What is the probability that a male offspring will have hemophilia? c.

- 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.…arrow_forwardWrite the genotype for each person based on : -Homozygous for B allele -Heterozygous for A allele -Type O -Type A and had a type O parent -Type AB -Blood that can be donated to anybody -Can only received blood from a type O donor There is a couple, the blood type of a male is A+ and the female is o+. What are all the possible blood types of their children in the future? Illustrate the inheritance in a Punnett Square showing all the possible blood types from the offspring of the male and female.arrow_forwardIn this part, you will work out on X-linked traits. Remember that males have only one X chromosome and females have two. For X-linked recessive, use the following designations: XA= normal Xa= the trait (a genetic disease or abnormality) For X-linked dominant, use the following designations: XA= the trait (a genetic disease or abnormality) Xa= normal Determine if the pedigrees below can be for a trait that is X-linked recessive. Write the genotype next to the symbol for each person in the pedigree below. A. Is it possible that this pedigree is for an X-linked recessive trait? B. What can you conclude about the children of mothers affected with an X-linked recessive characteristic? C. What can you conclude about the father of an affected female?arrow_forward
- Two people are planning to have children together. Each person is heterozygous for the gene “G”. Using this letter, first list all the possible gametes that the two people can produce. Next, write all the possible genotypes and phenotypes for their offspring, using the correct genetic terminology (e.g., “genotype is homozygous dominant” “phenotype is dominant”). HINT: Use the gametes to construct a Punnett square and predict the possible offspring (you do not need to include the Punnett square in your answerarrow_forwardDefine by giving an example : Allele.arrow_forwardplease DEFINE your genotypic symbols, then list the most probable genotype of each of the individuals indicated.
