In a certain plant, leaf size is determined by fourgenes whose alleles assort independently and actadditively. Thus, alleles A, B, C, and D each add4 cm to leaf length and alleles A′, B′, C′, andD′ each add 2 cm to leaf length. Therefore,an AA BB CC DD plant has leaves 32 cm longand an A′A′ B′B′ C′C′ D′D′ plant has leaves16 cm long.a. If true-breeding plants with leaves 32 cm longare crossed to true-breeding plants with leaves16 cm long, the F1 will have leaves 24 cm longand the genotype AA′ BB′ CC′ DD′. Listall possible leaf lengths and their expectedfrequencies in the F2 generation produced fromthese F1 plants.

In a cross in Drosophila, a female heterozygous for the autosomallylinked genes a, b, c, d, and e (abcde/ + + + + +) was testcrossedwith a male homozygous for all recessive alleles (abcde/abcde).Even though the distance between each of the loci was at least3 map units, only four phenotypes were recovered, yielding thefollowing data: Phenotype No. of Flies+ + + + + 440a b c d e 460+ + + + e 48a b c d + 52 Total = 1000 Why are many expected crossover phenotypes missing? Can anyof these loci be mapped from the data given here? If so, determinemap distances.
In the model plant Arabidopsis thaliana, the following alleles were used in a cross: T = presence of trichomes t = absence of trichomes D = tall plants d = dwarf plants W = waxy cuticle w = nonwaxy A = presence of purple anthocyanin pigment a = absence (white) The T/t and D/d loci are linked 26 m.u. apart on chromosome 1, whereas the W/w and A/a loci are linked 8 m.u. apart on chromosome 2. A pure-breeding double-homozygous recessive trichomeless nonwaxy plant is crossed with another pure-breeding double-homozygous recessive dwarf white plant. a. What will be the appearance of the F1? b. Sketch the chromosomes 1 and 2 of the parents and the F1, showing the arrangement of the alleles.c. If the F1 is testcrossed, what proportion of the progeny will have all four recessive phenotypes?
If the map distance between genes A and B is 10 map units and the map distance between genes B and C is 25 map units, How can I identify the map distance between genes A and C.
In rice, plants homozygous for the recessive allele sd1 are relatively short in stature; heterozygotes are of normal height. Plants carrying one copy of a dominant allele, Xa4 (corresponding to a second gene located on a different chromosome), are resistant to bacterial blight. Note that both the sd1 and Xa4 alleles would be considered "mutant" alleles in this scenario. A farmer obtained two pureline plants (one is homozygous for the sd1 mutant and the other is homozygous for the Xa4 mutant) and crossed them. Assume both pureline plants have identical alleles at all other loci, and no other mutant alleles are present in these two plants, which of these statements is correct? O All the progeny will be susceptible to bacterial blight and will be short. O When a progeny plant from the cross goes through meiosis, gametes will either contain sd1 or Xa4 alleles, but never both. O When a progeny plant from the cross goes through meiosis, four possible types of gametes that may form, and the…
Pigments in some bears are the result of epistasis between 2 genes. The black coat color is only produced when both wildtype forms of genes D and E are present. When gene D (D-ee) is wildtype alone, offspring are white. When gene E (ddE-) is wildtype alone, offspring are brown. When no wildtype alleles are present (ddee) offspring are all white. Based on this describe the relationship between the genes D and E. Group of answer choices A-D is dominant to E B- E is dominant to D C- D is epistatic to E D- E is epistatic to D

In a species of roses, the alleles RP and RR code for pink roses and red roses, respectively. In this case, the wild-type phenotype is red roses in which the locus exhibits a paramutation. The presence of RP with RR leads to a paramutation of RR to RP", which results in pink roses. This paramutation is 100% penetrant. If a heterozygous rose is crossed with a homozygous red rose, what is the phenotypic ratio of the offspring? O % pink and % red none pink and all red O all pink and none red O % pink and red
The alleles his-5 and lys-1, found in baker’s yeast, result in cellsthat require histidine and lysine for growth, respectively. A crosswas made between two haploid yeast strains that are his-5 lys-1and his+ lys+.
