Q4. You conducted an experiment similar to Morgan's fruit fly but you used honey bee instead. You are thus following 2 genes, the wing size Long (L) and short (1) and body color Yellow (Y) and black (y). You crossed YyLI x yyll and obtained 4,000 offspring. You counted the offspring classes and found the following distribution as follows: 1200 YyLl individuals 1190 yyll individuals 800 Yyll individuals 810 yyLl individuals a) what is the phenotype of each class of offspring? b) Which classes are of the parental type and which are the recombinant types? c) What is the recombination frequency between both genes? d) What is the map distance in cM and in map units between both genes? When you counted the offspring, you also collected data on a third gene coding for antenna shape. The gene has 2 alleles in the population, bended antenna (B) and straight antenna (b). You found a distance of 13 cM between the gene for antenna shape and that for wing size, and 24 cM between wing shape and body color. Place the 3 genes in the correct order and indicate the distances between them.

Help me create a pedigree of this information: Pedigree analysis: Generation 1: Normal parents (AA x AA) Generation 2: Carrier parents (AA x AS) Generation 3: Affected child (AS x AS) Generation 4: Affected grandchild (SS) This pedigree has two normal parents in the first generation. Second generation carriers carry the sickle cell trait from one parent. The disease is 25% more likely to be inherited in the third generation if both parents have the 'S' allele. If both parents have the 'S' allele, their children will have sickle cell anemia in the fourth generation

Neep help ASAP. A red flowered plant was crossed with a blue flowered plant and produced all purple flowered plants. When the purple flowered plants were crossed with each other they produced 5 red plants, 5 blue plants, 20 deep purple plants, 20 light lilac plants, and 30 purple plants How many genes are involved in the color production? Assume that red color is caused by an A allele and blue color by a B allele and determine the likely genotype of the plants in the F2 generation.
While sitting at home during Movement Control Order (MCO) because of pandemic covid19, observe two different traits of a couple in your family (eg. your mom & dad or your sister & her husband or your brother & his wife, etc). Draw a genetic cross that involves cross of the parents with the chosen 2 pairs of their contracting traits. Imagine that the cross obeys the Mendelian Laws, show the cross and gametes production for each generation (P, F1 and F2). By Using a Punnet square as symbolic representation of the results for the cross, determine the phenotypes, genotypes, phenotypic ratio and genotypic ratio of F2 generation in the family.
must answer all other don't answer i need all part solvve Two pea plants are crossed, which are purebred. A father is round, terminal, violet and wrinkled, while the other expresses the phenotypes alternate rough, axial, white, and swollen.

(b) In the results of F2, what phenotype will appear more often? Write a mathematical expression that predict the probability of occurrence of said phenotype.

Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
