The European land snail, Cepaea nemoralis, exhibits 3 phenotypes in shell color; brown, pink, and yellow. Shell color is controlled by one gene that has only two alleles. Brown (B) is dominant to yellow (b) and pink is the heterozygous condition. In one population of 520 snails, the following color phenotypes were recorded: 236 brown, 231 pink and 53 yellow. What are the actual allelic frequencies?

. In four-o’clocks, the allele for red flowers is incompletely dominant to the allele for white flowers, so heterozygotes have pink flowers. What ratios of flower colors would you expect among the offspring of the following crosses: (a) pink × pink, (b) white × pink, (c) red × red, (d) red × pink, (e) white × white, and (f) red × white? If you specifically wanted to produce pink flowers, which of these crosses would be most efficient?
Within a mouse population, the black fur allele (B) is dominant to the white fur allele (b) and the short whisker allele (S) is dominant to the long-whisker allele (s). A heterozygous black-furred short-whiskered mouse is crossed with a homozygous white-furred long-whiskered mouse. What percentage of the offspring will be black-furred with long whiskers?
Given a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: What proportion of the offspring will phenotypically resemble the first parent? What proportion of the offspring will genotypically resemble the second parent? How many phenotypes can be expected from the cross?
In corn plants, a dominant allele Z inhibits kernel color, while the recessive allele z permits color when homozygous. At a different locus, the dominant allele X causes purple kernel color, while the homozygous recessive genotype causes red kernel color. If corn plants heterozygous for both the Z and X genes are crossed, what are the chances that the offspring will have purple kernels? Enter your answer as a decimal fraction in the box (e.g. 0.25).
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
In rabbits, the dominant allele B causes black fur and the recessive allele b causes brown fur; for an independently assorting gene, the dominant allele R causes long fur and the recessive allele r causes short fur. A homozygous rabbit with long, black fur is crossed with a rabbit with short, brown fur, and the offspring are intercrossed. In the F2, what proportion of the rabbits with long, black fur will be homozygous for both genes? Show drawings and solution.
Using the example of pea color in Mendel’s pea plants, can you devise equations to determine the allele frequencies of A and a from the genotype frequencies of aa, Aa, and AA?
In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The allele for tall (D) is dominant to the allele for dwarf (d), and the allele for purple (P) is dominant to the allele for white (p). A tall plant with purple flowers crossed with a tall plant with white flowers produces 3/8 tall purple, 1/8 tall white, 3/8 dwarf purple, and 1/8 dwarf white. What is the genotype of the parents? a. Dd Pp x Dd pp b. DD Pp x dd pp c. DD Pp x dd Pp d. Dd Pp x Dd Pp e. Dd pp x dd Pp
In birds, wingspan is determined by two genes, one with complete dominance of one allele over the other, one with additive effects. Birds with genotype aabb has 16 cm long wingspan, whereas those with AABB has 20 cm long wingspan. A cross between AABB and aabb parents produced F1 with 19cm wingspan. Crossing the F1s produced F2 with the following phenotypes (in cm): 20.0 19.6 18.3 20.0 19.1 18.7 18.2 17.3 16.0 19.2 17.8 18.4 19.3 19.5 20.0 19.7 Determine the values of the following: NOTE: write the formula and the final answer Mean of the data Variance of the data Standard deviation According to these data, which wingspans are within one standard deviation of the mean?
Most of the individuals of a certain wildflower population have yellow flowers, although a few are white-flowered. Crosses have demonstrated that allele for yellow flower (Y) is dominant over the allele for white (y). If two heterozygous yellow-flowered plants are crossed, what fraction of the offspring do you expect to be white? Show your solution.
