An individual with a form of red-green color blindness processes a genetically inherited trait that makes it difficult to distinguish red and green color hues. Red-green color blindness tends to skin generations and it is found much more often in men than in women. If a man who was normal and a woman who is a carrier for this form of colorblindness have a child, when the probability that the child will be red-green colorbind is: -0% -25% -50% -75% -100%

Cystic fibrosis is an autosomal disease that mainly affects the white population, and 1 in 20 whites are heterozygotes. Genetic testing can diagnose heterozygotes. Should a genetic screening program for cystic fibrosis be instituted? Should the federal government fund it? Should the program be voluntary or mandatory, and why?
Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child? If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)? NOTE: Draw a punnet square or show your work.
Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.
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
A is a dominant gene for normal pigment, and a is its recessive allele for albinism (and pink eyes). B is a dominant gene for brown eyes, and b is its recessive allele (blue). What is the mother's genotype if two brown-eyed parents have fraternal twins, one with blue eyes and one with pink eyes (albino)? a. AaBb b. AaBB c. aaBb d. aabb e. AABB
In humans, the allele for brown (B) eye color is dominant to the allele which causes blue (b) eyes. If a brown-eyed man, whose father had blue eyes marries a brown-eyed woman and the first baby of this couple has blue eyes, answer: What is the genotype of the man? What is the Genotype of the woman? What is the expected genotypic and phenotypic ratio among all possible children?
The letter that accompanies each trait is representative of the dominant allele. This is the letter you will use when recording the genotypic information for each trait. Read through the descriptions of the trait and determine which phenotype you express. Record your phenotype. Next, determine the genotype. If you express the dominant phenotype, you cannot determine the second allele you carry, so you must list the two possible genotypes. Record this down Question: Eye color (B): Inheritance of eye color is controlled by multiple genes, but people having the homozygous recessive genotype have blue eyes. People who have a dominant allele may have different shades of brown, hazel, or green eyes.
For the Y-linked gene, use T for hypertrichosis. For X-linked genes, use the letters H for blood trait and E for eye trait. Krisha, a carrier of the genes for hemophilia and colorblindness, is married to Kyle who is color blind, having normal red blood cells. Veronica (Krisha & Kyle's daughter), turned out to be a carrier for both genes. Julian has hypertrichosis and is married to Josie. Both do not exhibit any allele for color blindness and never had any history for hemophilia. Bernard (Julian & Josie's son) will be married to Veronica. What are the complete genotypes of the following persons: a. Krisha b. Kyle c. Veronica d. Julian e. Josie f. Bernard g. Josie & Bernard's baby
A woman who is a carrier for red-green colorblindness marries a man who is colorblind. If they have a daughter, what are the chances she will be colorblind
In humans, a dimple in the chin is a dominant characteristic controlled by a single gene. A man who does not have a chin dimple has children with a woman with a chin dimple whose mother lacked the dimple. What proportion of their children would be expected to have a chin dimple? A man with a chin dimple and a woman who lacks the dimple produce a child who lacks a dimple. What is the man’s genotype? A man with a chin dimple and a non-dimpled woman produce eight children, all having the chin dimple. Can you be certain of the man’s genotype? Why or why not? What genotype is more likely, and why?
Red-green color blindness is an X-linked recessive disorder. If Allison is heterozygous (a carrier), and her husband, Michael, is NOT colorblind. What is the chance that their female children will be colorblind? (Note: you are calculating the probability for their FEMALE children only, in other words if they have 1 female child, what is the probability that she will be born colorblind?) 0% 25% or 1/4 50% or 2/4 75% or 3/4 100% or 4/4
If one parent is heterozygous for an autosomal allele (Aa), and the other is homozygous for the recessive allele (aa), what is the probability that their child will inherit the dominant allele and have the associated trait? 50 percent 75 percent 0 percent 100 percent
