1. A plant with red flowers is crossed with a white-flowered plant of the same species. All the seeds, when grown, produce plants with red flowers. Assuming that the flower color is controlled by a single pair of alleles, which allele is dominant and which is recessive? 2. How does inbreeding increase the incidence of recessive disorders in a population? 3. Why does an individual always have only two alleles for a given gene? 4. In cats, the allele (S) for short fur...

A red flowered plant is crossed with a white flowered plant. All of the F1 plants produce red flowers. When the F1 plants are allowed to self-pollinate, 389 of the F2 plants have red flowers and 141 have white flowers. What are the genotypes of the parental and F1 generation plants? A. P:Red = RR, white = rr; F1 = Red RR and Rr B. P:Red =Rr, white = rr; F1 = Red Rr and rr C. P: Red =...

Clownfish exhibit three phenotypeni red, yellow, and orange. If a red clownfish is mated with a yellow clownfish, the resulting progeny are all orange. a. What type of inheritance pattern do you suspect? incomplete dominance b. Construct a Punnett square to illustrate a cross between two RRRR orange clownfish. (make up letters to represent the alleles) 15. RRR Genotypic ratio: la: Phenotypic ratio: 1: 2!! There are 4 alleles (C.ch, ch, and e) of the gene for coat...

In the tubular flowers of foxgloves, wild-type coloration is red while a mutation called white produces white flowers. Another mutation, called peloria, causes the flowers at the apex of the stem to be huge. Yet another mutation, called dwarf, affects stem length. You crossed a red-flowered plant (gene symbol, r) to a plant that is dwarf (gene symbol, d) and peloria (gene symbol, p). All of the F1 plants are tall with red, normal stem flowers. You cross an F1...

Question 1 (1 point) In a species of flowering plant, petal color is determined by one gene with two alleles, R and W. Individuals homozygous for allele R have red petals, and those homozygous for allele Whave white petals. Ris dominant to W. You cross a pure- breeding red flowered plant with a pure-breeding white flowered plant to create an F1 generation. You then cross two individuals from the F1 generation to create an F2 generation. What proportion of the...

1. In a cross between two pure-breeding varieties of radish, one with red and the other with white roots, all the F1 progeny had purple roots. The F2 obtained by selfing the F1 segregated as follows: Red Purple 80222 White 98 Two models (A and B) were suggested to account for these results:- A) Root colour is controlled by a single gene with two alleles showing incomplete dominance B) Root colour is controlled by two unlinked genes showing (recessive) epistasis....

In a different plant species, flower color is controlled by two genes that contribute equally to the final flower color. Plants with red flowers have the genotype: CRCR DRDR, while plants with white flowers have the genotype: CWCW DWDW. A red flowering plant was mated to a white flowering plant and all of the F1progeny had pink flowers. These pink flowered F1 plants were allowed to self-fertilize to produce F2progeny. What is the genotype of the F1 plants that produced...

6. In Cross 1, a yellow eyed, long wing fruit fly from a pure breeding strain is mated to a red eye, short wing fruit fly from a pure breeding strain. All of their offspring (F1) had red eyes and long wings. In Cross 2, one of the F1 offspring is mated to a fly with yellow eyes and short wings, and this cross gave the following F2 population: 194 flies with long wings and red eyes, 796 flies with...
