A strain of plants has a mean height of 24 cmcm. A second strain of the same species from a different geographical region also has a mean height of 24 cmcm. When plants from the two strains are crossed together, the F1F1 plants are the same height as the parent plants. However, the F2F2 generation shows a wide range of heights; the majority are like the P1P1 and F1F1 plants, but approximately 4 of 1000 are only 12 cmcm high, and about 4 of 1000 are 36 cmcm high.

You make a test cross between an F1 plant that is heterozygous for two dominant resistance genes (R1 and R2) and a line that is homozygous recessive at both loci, and inoculate the progeny with a pathogen race that is avirulent on both R1 and R2 (i.e., it carries avirulence genes Avr1 and Avr2).You get 50 susceptible progeny out of 200 test cross progeny. (a) What is the linkage phase for these two genes? (b) What is the recombination distance?
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 ] > >

You carry out a trihybrid cross (a cross in which the parental plants differ for three characters) between a tall pea plant with round, yellow seeds (TT RR YY) and a short pea plant with wrinkled, green seeds (tt rr yy). The parental plants are homozygous for all of the three characters. They are crossed to produce the F1 generation. Tall, round, and yellow are the dominant traits for each character. What will be the phenotypes of the F1 generation?
Nicotiana glutinosa (2 n = 24) and N. tabacum (2 n = 48) are two closely related plants that can be intercrossed, but the F1 hybrid plants that result are usually sterile. In 1925, Roy Clausen and Thomas Goodspeed crossed N. glutinosa and N. tabacum and obtained one fertile F1 plant . They were able to self-pollinate the flowers of this plant to produce an F2 generation. Surprisingly, the F2 plants were fully fertile and produced viable seeds. When Clausen and Goodspeed examined the chromosomes of the F2 plants, they observed 36 pairs of chromosomes in metaphase I and 36 individual chromosomes in metaphase II. Explain the origin of the F2 plants obtained by Clausen and Goodspeed and the numbers of chromosomes observed.
A homozygous strain of plants (P1) has a mean height of 12 cm. A second homozygous strain of the same species (P2) has a mean height of 36 cm. When plants from the two strains are crossed together, the F1 plants have mean height of 24 cm. The F2 generation from the F1 X F1 crosses shows a wide range of heights; the majority are like the F1 plants, but 4 of 1000 are only 12 cm high (shortest), and 4 of 1000 are 36 cm high (tallest). 2. What is the expected proportion of plants in the F2 that are as tall as the F1 plants? a. 37.5% b. 25% c. 50% d. 27.3%
You are studying three linked genes in snapdragons. The flower color locus is in the center. There are 8.3 cM between the flower color locus and the plant height locus. There are 12.4 cM between the flower color locus and the leaf type locus. The coefficient of coincidence is 0.8. Pure-breeding tall, red-flowered plants with fuzzy leaves were crossed to pure-breeding dwarf, blue-flowered plants with smooth leaves. The F1 were testcrossed. Calculate the proportion of the testcross progeny that are expected to have red flowers and fuzzy leaves. Round properly to 4 decimal digits. Answer:
In cucumbers, speckled fruit color (u') is dominant to uniform fruit color (u), and large spines (ss") are dominant to small spines (ss). These two genes are linked at a map distance of 20.4 m.u. A true-breeding cucumber plant with speckled fruit and large spines is crossed with a true-breeding plant with uniform fruit color and small spines. One of the F1 plants is crossed with a plant with uniform fruit color and small spines. What percentage of the offspring of this cross are expected to have uniform fruit color and small spines? 39.8% 10.2% 79.6% 20.4%
