Variations on a Theme by Mendel
Pea plants usually have white or red flowers. A strange pea-plant variant is found that has pink flowers. A selfcross of this plant yields the following
30 red flowers
62 pink flowers
33 white flowers

A cross between two red flower plants produces 2/3 progeny that are red and1/3 progeny that are yellow. What is the genotype of the red flower? Explain these unexpected ratios.
A diploid plant has red flowers, heavy seeds and large leaves. The plant is a heterozygous for the following three genes:flower color (gene “F”),seed weight (gene “S”),and leaf size (gene “L”).
This plant is testcrossed to a plant, which has white flowers, light seeds, and small leaves, the progeny of the testcross is as follows:
222
Red, heavy, large
228
White, light, small
224
Red, heavy, small
226
White, light, large
24
Red, light, large
26
White, heavy, small
25
White, heavy, large
25
Red, light, small

Question 9 options:
All three genes are on different chromosomes.
Genes S and L are linked, while F assorts independently.
Genes F and S are linked, while L assorts independently.
Genes F and L are linked, while S assorts independently.
Perform 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?

- Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?arrow_forwardThe 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?arrow_forwardIn the following cross, imagine that you have a female fly that has two Xs and one Y due to a nondisjunction event in her mother's germ cells. Draw out what the possible gametes are for both the female and the male and also a Punnett square showing the genotypes, phenotypes, and sex of the possible flies as a result of this cross.

- In a trihybrid cross in garden pea plants that differ in plant height (tall is dominant to dwarf), flower color (purple is dominant to white), and seed color (yellow is dominant to green), what is the probability of getting a tall plant with purple flowers and green seeds in the F2 generation. The three genes are on separate chromosomes. 3/16 9/16 27/64 3/64 9/64arrow_forwardO All three genes are linked, but need to do more crosses and data to determine the gene order. All three genes are linked with the flower color gene (F) in the middle. All three genes are linked with the seed weight gene (S) in the middle. All three genes are linked with the leaf size gene (L) in the middle.arrow_forwardIn an autotetraploid Chinese primrose (Primula sinensis L.), the gene controlling stigma color is very near the centromere of the chromosome carrying it. The allele G for green stigma is dominant to g for red stigmas. A homozygous green autotetraploid strain is crossed with a homozygous red autotetraploid strain. What is the genotype of the F1? Show the types of gametes the F1’s may be expected to form and derive the expected proportion of each. What phenotypic ratio of green to red is expected if: The F1’s are intercrossed? The F1’s are crossed with red plants If the G locus were 50 or more map units from the centromere, what types and proportions of gametes would the F1 be expected to produce? Derive the expected F2 phenotypic ratio.arrow_forward
- In roses, purple flower color is determined by the dominant P allele, while pp homozygotes are white. The presence of long stems is determined by the dominant S allele, while ss homozygotes have short stems. Both mutations are completely penetrant. A test cross was performed between a rose plant of unknown genotype with a white flowered, short stemmed rose plant (pp ss) and the following 200 progeny plants were obtained: 84 white flowers, long stems 16 purple flowers, long stems 82 purple flowers, short stems 18 white flowers, short stems Select the statements below that are TRUE. Select 2 correct answer(s) The P and S genes independently assort during meiosis. The map distance between P and S is 17 CM. The genotype of the progeny plants with purple flowers and short stems is PP ss. The map distance between P and S is 83 CM. The homologs in the plant with unknown genotype are p S and Ps.
