Monohybrid Cross: 1) In dogs, wire hair (S) is dominant to smooth (s). a. In a cross between a homozygous wire-haired dog with a smooth haired dog what are the genotypes and phenotypes of the F1 generation? b. If a brother and sister from the F1 generation are crossed what is the expected ratio of wire-haired to smooth-haired dogs produced from this cross?
Topic: Penetrance. Petal number is controlled by a single gene in merigonias. The gene has a completely dominant wild type allele F that makes a plant have five petals and a mutant recessive six petal allele(f). However the six petal trait is only 50% penetrant. You do the cross Ff x Ff. What fraction of the progeny do you have the 6 petals? what is the meaning for 50% penetrant.
7-8. Assume that white color is dominant over yellow color in squash. If pollen from the anthers of a heterozygous white-fruited plant is placed on the pistil of a yellow- fruited plant, show using ratios the genotypes and phenotypes you would expect the seeds from this cross to produce. Genotypes = 1/2 Ww 1/2 Ww = 1:1 ratio | Phenotypes = All white = 1:0 ratio Genotypes = 1/2 WW 1/2 ww = 1:1 ratio | Phenotypes = 1/2 white 1/2 yellow = 1:1 ratio Genotypes = 3/4 Ww 1/4 ww = 1:1 ratio | Phenotypes = 3/4 white 1/4 yellow = 1:1 ratio Genotypes = 1/2 Ww 1/2 ww = 1:1 ratio | Phenotypes = 1/2 white 1/2 yellow = 1:1 ratio
In the common daisy, genes A and B control flower color. Both genes have a dominant allele (A or B) and a recessive allele (a or b). At least one copy of each dominant allele is required for flowers to be colorful instead of white.

2/7 - <. Hair texture is an incompletely dominant trait in humans. The three phenotypes are curly, wavy and straight. Straight only occurs when both parents have straight hair. Curly hair also tends to follow this pattern. Only two wavy haired parents produce all three phenotypes. Please explain this observation using punnett squares. Curly x Curly straight x straight Wavy x wavy

Phenotype Ratio - Gentoype Ratio - 13. In guinea pigs, the allele for short hair is dominant over long hair. Two short haired guinea pigs are mated several times. Out of 100 offspring, 25 of them have long hair. What are the probable genotypes of the parents? (Show the cross to prove it!)
Monohybrid cross 1. In peas, tall|(T) is dominant to short(t). If a pure tall and a pure short plant are crossed, and the resulting offspring are crossed, how many of the F2 will be short if 120 plants are produced?
n corn, male sterility is controlled by maternal cytoplasmic elements. This phenotype renders the male part of the corn plants (i.e the tassel) unable to produce fertile pollen; the female parts, however, remain receptive to pollination by pollen from male fertile corn plants. However, the presence of a nuclear fertility restorer gene F restores fertility to male sterile lines sing the cardboard chips, simulate the crosses indicated below. Give the genotypes and phenotypes of the offsprings in each cross, and properly label the nucleus and the cytoplasm of each individual in the cross Legend male sterile cytoplasm Male fertile cytoplasm FF nucleus Ff nucleus ff nucleus A. Male sterile female x FF male Explain the phenotype of the offspring B. Male sterile female x Ff male Explain the phenotype of the offspring
Genetic cross with dependent assortment (linked traits). Repeat the previous problem but assume that the genes are located very close to each other on the same chromosome, and are therefore always linked (passed on together). Assume that in these individuals, each chromosome contains the dominant allele for one gene and the recessive allele for the other gene. Note: this is similar to the dependent assortment example in your notes, but the linkage is different.

A dominant gene (W) produces wire-haired texture in dogs; its recessive allele (w) produces smooth hair. A group of heterozygous wire-haired individuals are crossed and their F1 progeny are then test-crossed. Determine the expected genotyplc and phenotypic ratios among the test cross progeny:
