This tool can be used for educational purposes to facilitate understanding of genetics and traits inheritance in offspring.

In genetics, the genes are the hereditary units of life. Each gene has its alternative forms called…

Suppose two independently assorting genes are involved in the pathway that determines fruit color in squash. These genes interact with each other to produce the squash colors seen in the grocery store. At the first locus, the W allele codes for a dominant white phenotype, whereas the w allele codes for a colored squash. At the second locus, the allele Y codes for a dominant yellow phenotype, and the allele y codes for a recessive green phenotype. The phenotypes from the first locus will always mask the phenotype produced by the second locus if the dominant allele (W) is present at the first locus. This masking pattern is known as dominant epistasis. A dihybrid squash, Ww Yy, is selfed and produces 128 offspring. How many offspring are expected to have the white, yellow, and green phenotypes? number of white offspring: number of yellow offspring:

Match Genotype With Phenotype Consider a newly discovered organism that is bioluminescent. Scientists studying this animal have discovered that there are two enzymes necessary for the animal to glow, encoded by the bright and red genes. Furthermore, scientists have confirmed that for bioluminescence to be displayed, an individual must have at least one copy of the dominant allele for each gene, (B and R). Match the genotypes with their correct phenotypes, glowing or nonglowing. BBRR Bbrr bbrr Glowing BbRR bbRR BbRr bbRr Non-glowing BBRr BBrr C
Part 1: Make a three part process drawing (like a cartoon strip) to demonstrate Mendel’s Principle of Segregation. Use two parents with homologous chromosomes marked with alleles “A” and “a”. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes (indicate when this happens), and c) gametes from each parent combine at random to form diploid offspring Part 2: Use the cross Aa x Aa and a Punnett square to demonstrate Mendel’s Principle of Segregation. Circle and label these three action parts of the Principle of Segregation: a) parents are diploid, b) alleles separate to form haploid gametes and c) gametes from each parent combine at random to form diploid offspring. Write the expected genotypic and phenotypic ratios.

Shown in the pictures below are the degrees of dominance in the inheritance of flower color in some plants. *Based on the phenotypes (or maybe genotype), differentiate between complete dominance, incomplete dominance, and codominance. Be able to discuss the difference briefly but concisely. You may also refer to the definition.
. BRCA1 is a bi-allelic gene (let's call the two alleles as C and c) that is inherited on an autosome. The C allele is completely dominant over c, expressing breast cancer as a phenotype. Eye color is determined by two independently assorting bi-allelic genes, B (alleles B and b) and G (alleles G and g), such that the Ballele shows dominant epistasis over the G and g alleles. Brown-eyed individuals have at least one copy of the B allele, green eyed individuals have at least one G allele, while blue eyed individuals have neither B nor G. A blue-eyed person whą is a heterozygote carrier for the BRCA1 gene has 3 children with a brown-eyed person (heterozygote for both B and G genes) who does not have breast cancer. (a) What are the possible genotypes and phenotypes of all their possible children? What are their respective probabilities of being observed (please write all genotype and phenotype probabilities)? (b) What is the probability that all three children will be blue-eyed and not…
Mutant female: yellow body and purple eyes. Male: Normal Use: https://www.sciencecourseware.org/FlyLabJS/ Which mutant alleles are dominant? Which mutant alleles are recessive? Which mutant alleles are sex-linked? Which mutant alleles are autosomal? Can you tell at this point if the two genes are linked? Show the results of the dihybrid analysis. Are genes segregating independently? What is the evidence for or against this? Show the crosses you will use to obtain the mapping data. For the mapping crosses, Write out the crossing scheme and make a table of the results (ignore sex in this table, combine the male and female progeny). Identify the parental classes and the recombinant classes. For a 3-point cross, identify the double cross overs. Show your calculations for the recombination frequencies between the three genes (for the 3-point cross) or the two genes (for the two-point crosses). Draw a map of the Drosophila chromosomes 2, 3, and X, including…

Name: Class Date Polygenic Inheritance: Cat Coat Color Read aboutthe inheritance of cat coat color In each cat below, predict the phenotype of each genotype and color in each catl Make sure you indicate whether each cat is male or female One gene that affects coat color in cats is an x linked gene we'll call the pigment gene. One allele causes black fur (X) and one allele gives the cat orange fur (X"). These alleles act in a codominant manner, because when a cat has two different alleles (XB Xb), the cat has a pattern called tortoise shell, where the cat has both orange and black hairs. The Y chromosome does not have this coat color gene There is another gene that affects coat color in cats called the piebalding gene. This gene is on an autosomal chromosome and the alleles affect the amount of white patches that appear in the cat's coat, Some cats (ss) have o white patches and their other colors are blended, not patchy. Some cats (SS or Ss) have white patches and their other colors are…
In Drosophila melanogaster body color is controlled by one gene while wing shape is controlled by a second gene. Gray body color is dominant to black body color, and normal wings are dominant to vestigial wings. Flies homozygous for gray body color and vestiial wing are crossed with flies homozygous for black body color and normal wings Compare the possible F2generation genotypes and phenotypes and proportions if these two traits are autosomally linked in comparison to the non-linked How does your answer change if one of the original parents is homozygous for gray body color and normal wings while the other has black body color and vestigial wings

In mice, gene A is epistatic to gene B. Dominant allele "A" allows for pigment to be transported to the fur; recessive allele "a" prevents the transport of pigment to the fur, resulting in an albino mouse. Dominant allele "B" gives agouti fur color; recessive allele "b" gives black fur color. What phenotype would you expect from a mouse with "aaBb" genotype? * A.black and white fur B.albino fur C. agouti fur D. black fur
