Fungal Infections

Fungal infection can be defined as an infectious disease caused by fungi. A fungal infection is also referred to as mycosis. Fungal infections are contagious, spreading from person to person. Mycosis can be contracted even from an infected animal or contaminated soil. The most common symptom is skin rashes and vaginal discharge in females.

In maize trisomics, n + 1 pollen is not viable. If adominant allele at the B locus produces purple colorinstead of the recessive phenotype bronze and a B b btrisomic plant is pollinated by a B B b plant, whatproportion of the progeny produced will be trisomicand have a bronze phenotype?
Waxy endosperm (wx), shrunken endosperm (sh) and yellow seedling (v) are encoded by three recessive genes in corn that are linked on chromosome 5. A corn plant homozygous for all three recessive alleles is crossed with a plant homozygous for all the dominant alleles. The resulting F1 are then crossed with a plant homozygous for the recessive alleles in a three point test cross. The progeny of the test cross are: wx sh WX SH V WX SH V Wx sh WX sh V SH v SH V V 87 1,515 94 WX 1,531 3,479 292 WX Wx sh v 3,478 280 a. Determine the order of the genes on the chromosome. b. Calculate the map distances between the genes. c. Determine the cc and I.
In a certain plant, the dominant form of gene B codes for blue fruit, while the recessive form results in pink fruit. The dominant form of another gene, E, inhibits the activity of the enzyme coded for by gene B, resulting in white fruit, while the recessive form is unable to inhibit this enzyme and results in colored (i.e., blue or pink) fruit. A doubly-homozygous dominant white-fruited plant is crossed with a pink-fruited plant. The F1 progeny were then self-crossed to generate the F2 generation. Determine the ratios of genotypes and phenotypes for each generation.
In 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. Each of the F1 GGgg plants would obtain 12 gametes which are 2GG, 8Gg, and 2g. How were these obtained?
A pea plant is heterozygous for three genes (Tt Rr Yy), whereT = tall, t = dwarf, R = round seeds, r = wrinkled seeds, Y = yellowseeds, and y = green seeds. Tall, round, and yellow are the dominanttraits. What is the probability that an offspring from self-fertilizationof this plant will be tall with wrinkled, yellow seeds?
At the molecular level (with regard to loss-of-function alleles), explain why the ttvv homozygote has an ovate seed capsule.
Mendelian ratios are modified in crosses involving autotetraploids.Assume that one plant expresses the dominant trait greenseeds and is homozygous (WWWW). This plant is crossed to onewith white seeds that is also homozygous (wwww). If only onedominant allele is sufficient to produce green seeds, predict theF1 and F2 results of such a cross. Assume that synapsis betweenchromosome pairs is random during meiosis.

You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob. Crossing the plant with heterozygous purple flowered pea plant (Pp) Crossing the plant with homozygous dominant purple flowered pea plant (PP) d.

Two genes of a flower, one controlling blue (B) versus white(b) petals and the other controlling round (R) versus oval (r)stamens, are linked and are 10 map units apart. You cross ahomozygous blue oval plant with a homozygous white round plant. The resulting F1 progeny are crossed with homozygouswhite oval plants, and 1,000 offspring plants are obtained.How many plants of each of the four phenotypes do youexpect?
Summer squash exist in long, spherical, or disk shapes. When atrue-breeding long-shaped strain was crossed to a true-breedingdisk-shaped strain, all of the F1 offspring were disk-shaped. Whenthe F1 offspring were allowed to self-fertilize, the F2 generationconsisted of a ratio of 9 disk-shaped to 6 round-shaped to 1 longshaped. Assuming the shape of summer squash is governed by twodifferent genes, with each gene existing in two alleles, propose amechanism to account for this 9:6:1 ratio
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.
