Question
In butterflies, blue wings (B) are dominant over yellow wings (b), and stripes (S) are dominant over no stripes (s). These genes for these two characteristics assort independently. A homozygous butterfly with yellow wings and no stripes is crossed with a homozygous butterfly that has blue wings and stripes. Afterward, individuals from this F1 generation were crossed obtaining a total of 272 butterflies as follows: 135 blue-winged butterflies with stripes, 55 blue with no stripes, 57 yellow with stripes, and 25 yellow without stripes.

A heterozygous female fly with a genotype w* s*/ws (w* and s* are wild-type alleles) is crossed to a male wild-type fly.

- Tomato Plants In tomato plants, round fruit (R) is dominant to oval fruit (r). Pure breeding plants with red and round fruit (FFRR) were crossed to pure breeding plants with yellow and oval fruit (ffrr). The red and round F1 progeny were then testcrossed to plants that were homozygous recessive for both genes (ffrr) with the following results: Phenotypes Number of Offspring Red and round 2 255 Red and oval 290 Yellow and round 310 Yellow and oval 2 145 Convert the expected phenotypic ratio from Part A into the expected probability for each of the four phenotypes and record them in the table below. Calculate the probability for each of the four phenotypes observed in the cross from the data presented at the beginning of the question by dividing the number of progeny in each class by the total number of progeny and record these in the table below.

The F1 all had red eyes. The F1s were intercrossed to produce F2 generation that consisted of 175 red eyed:81 white eyed. Provide the genetics of inheritance of this trait. Provide the genotypes for the F1s and F2s of this cross.arrow_forwardCoat color in mice is influenced by two genes, one for color (A) and one for the amount of pigment production (C). Mice with the wild type agouti coat color have a yellowish to brownish color. Mice also have a gene that determines the amount of pigment the hair produces. Multiple crosses were made between male and female mice that were each heterozygous for both traits (AaCc). The data table shows the number of mice of each coat type. Calculate the average F1 generation coat color to answer the question. Which of the following is the most probable interaction between the two genetic loci, A and C, based on the average F1 ratio results? A - The two loci show an epistatic pattern with the loci C epistatic to loci A. B - The two loci show a codominant pattern with both loci affecting coat color. C - The two loci interact in a Mendelian pattern with A being completely dominant over C. D - The two loci show an incomplete dominance pattern with neither loci A nor C being dominant.arrow_forward
- A is dominant over a and B is dominant over b. Genes A/a and B/b assort independently. The parental cross (P) is between true- breeding (homozygous) strains (AA bb x aa BB). The resulting F1 offspring would be [Select ] A F1 x F1 cross gives the F2 generation. The ratio of phenotypes in the F2 generation can be described as [ Select ] In the phenotypic ratio, what number refers to individuals that are: dominant for both traits? [ Select ] recessive for both traits? [Select ] To what phenotypes do the "3"s in the ratio refer? [ Select ] > >arrow_forwardPerform two consecutive crosses similar to those of Mendel for the following individual plants. Plants with round seeds (RR) are crossing with plants with wrinkled seeds (rr). After the first cross, cross the offspring together to generate F2 offspring. What are the genotypic and phenotypic ration of F2?arrow_forwardYou are doing a cross with Drosophila using the following two traits. Curly wings is dominant over straight wings, and round eyes is dominant over elliptical eyes. You cross a female fly that is known to be heterozygous for both genes with a male that is heterozygous for the wing gene but has elliptical eyes. This cross produces 74 flies with curly wings and round eyes, 61 with curly wings and elliptical eyes, 24 with straight wings and round eyes, and 21 with straight wing and elliptical eyes. Calculate the expected phenotype ratios for this cross, then use the chi-square test to see if the observed data are consistent with the expected numbers.arrow_forward
