A farmer is interested in an interesting colour in his lilies. Colour in lilies is controlled by a single autosomal gene (Gene H) with two alleles. The H-allele results in a purple flower, while the recessive allele results in a white flower. The farmer has a plant that has purple flowers. Can you suggest how the farmer can determine the genotype (HH or Hh) of his purple flowered plant in a single cross? Describe this cross and provide details on how you would interpret the results.

The text outlines some of the problems Frederick William I encountered in his attempt to breed tall Potsdam Guards. a. Why were the results he obtained so different from those obtained by Mendel with short and tall pea plants? b. Why were most of the children shorter than their tall parents?
The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
A farmer is interested in a novel colour pattern in beans. This trait is controlled by a single autosomal gene (Gene G) with two alleles. The G-allele results in a striped bean, while the recessive g-allele causes a brown bean. The farmer has a plant that has striped beans. Can you suggest how the farmer can determine the genotype (GG or Gg) of his bean plant in a single cross? Describe this cross and provide details on how you would interpret the results
A breeder is interested in a new coat colour in mice. This trait is controlled by a single autosomal gene (Gene T) with two alleles. The T-allele results in a yellow coat colour, while the recessive allele causes a cream coat colour. The breeder has a yellow mouse. Can you suggest how the breeder can determine the genotype (TT or Tt) of his mouse in a single cross? Describe this cross and provide details on how you would interpret the results.
Fruit fly body color is wild type (meaning normal) Gray = B+ and black = b Fruit fly wing type is wild type normal wings = vg+ and vg = vestigial A fly which was heterozygous for both traits was crossed with a fly that was recessive for both traits. Write the genotype and phenotype that would be expected from this cross. Write the genotype and phenotype percentages that would be expected from this cross.
In tomatoes, red fruit color (R) is dominant over yellow fruit color (r). Do the following crosses: Rr x rr Rr x RR rr x RR Rr x Rr rr x Rr rr x rr Show your Punnett square for each cross. For each cross also show the genotypic and phenotypic ratios.
A cross is made between two plants with five independently assorting genes. SHOW YOUR WORK AA Bb Dd Ee hh X Aa Bb Dd ee Hh What is the probability of obtaining a plant with the genotype AA BB Dd ee Hh?
A plant geneticist is examining the mode of inheritance of flower color in two closely related species of exotic plants. The first species may have two pure-breeding lines—one produces a distinct red flower; and the other produces flowers with no color at all, or very pale yellow flowers. However, she cannot be sure. A cross of these varieties produces all pink-flowered progeny. The second species exhibits similar pure-breeding varieties; that is, one variety produces red flowers; and the other produces an albino or very pale yellow flower. A cross of these two varieties, however, produces orange-flowered progeny exclusively. Analyze the mode of inheritance of flower color in these two plant species.
In a species of flowers, blue petals are dominant over purple petals, and a long stem is dominant over a short one. Cross a flower that is heterozygous for both traits with a flower that is homozygous recessive for petal color and homozygous dominant for stem length. Report the genotype and phenotype. *Write your answers in ratio non-reduced form (Example 16:8) Genotype Phenotype
We have crossed true-breeding flies today. Wild type to mutant. Their phenotypes were wt and vg se. (Let’s not worry about males and females for now, just assume both genes are autosomal, which is normal in a Mendelian experiment). The results of a cross are phenotypes. I will be asking you for numbers or a ratio of phenotype numbers you expect to see in the offspring from this cross. To answer this, you’ll need to start with the genotypes of parents, then write their gametes, then write the offspring genotypes, then get the phenotypes based on them. Predict the results of this cross: In case both mutations are recessive; In case both mutations are dominant; In case vestigial wings are recessive and the sepia eyes are dominant.
In peas, yellow pods are dominant to green pods. Show the results of a cross between a pure yellow plant and a hybrid yellow plant.
Diagram the P1 and F1 crosses, using Mendelian notation, to show the possible genotypes found in each generation. (Remember a diagram is just the cross itself, not the progeny).
