A horticulturist sought to test the hypothesis that flower bolor in the plant blue-eyed Mary Collins parviflorais controlled by a single gone locus where paired alles have a dominant-recessive relationship. The horticulturist crossed two plants that produced flowers of different colors, white and magenta, which he believed were true breeding The horticulturist observed that all of the plants resulting from his cross produced blue flowers. When the horticulturist crossed the F1 plants with each other he obtained the following F2...

Question 1. Consider 3 gene loci in the pea plant. Locus 1 affects seed color; allele G for green, g for yellow. Locus 2 affects seed shape; allele R for round, r for wrinkled. Locus 3 affects flower color; allele B for red, b for white. Each uppercase allele is completely dominant to their corresponding lowercase, recessive allele. Each locus is on a different non-homologous chromosome; so, the loci segregate or sort independently from each other during meiosis. Two parent...

17. A diploid plant is a dihybrid for flower color (gene “R”)
and leaf size (gene “L”). Its
phenotype is red flowers and large leaves. This plant is crossed to
a tester plant (which has
white flowers and small leaves). The progeny is as follows:
23 Red, large
25 White, small
230 Red, small
235 White, large
What can be concluded about the linkage relationship of the loci in
the dihybrid parent?
A) Genes R and L are unlinked
B)...

please answer two question below
thankyou
e) 9; 9 3. In another plant species, the presence and type of hairs on the plant are controlled by epistatic interaction between two independently assorting genes. Gene C determines whether the plant has hairs (dominant) or not (recessive); Rene D determines whether the hairs are straight (dominant) or curly (recessive). In a cross between a straight-haired plant and a curly- haired plant, 1/4 of the offspring have no hairs. 3/8 have straight hairs,...

1. In loppins (fictitious diploid invertebrates), ear shape is controlled by two genes with two alleles each; upright ears (F) is dominant to floppy ears (f), and double-pointed ears (P) is dominant to single-pointed ears (p). Moreover, due to genetic interactions, floppy ears are always single-pointed. A loppin with floppy ears is crossed to a loppin with upright single-pointed ears, and the phenotypic ratios in the offspring are 2 floppy : 1 double-pointed upright : 1 single-pointed upright. What are...

please answer question 1-4 with a breif explanation
thankyou
1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2. In a certain species...

1. You want to determine whether three prairie dog genes are linked, and if so what is the order of the genes and how many map units are they away from each other. Capital letters are dominant: L = long necked, I = short-necked, G = gray fur, g = brown fur, R = red eyes, r = pink eyes. True-breeding parentals of opposite phenotypes were bred to produce the F1 hybrids, then the F1 hybrids were test crossed to...

(1) One of the standard techniques to determine whether two loci are physically close to one another on the same chromosome is to conduct a "dihybrid cross", a cross of two individuals that are heterozygous at both loci. For example if the two loci have alleles A and a at the first locus and B and b at the second locus then crossing...
