In corn plants, a dominant allele (1) inhibits the expression of kernel color, while the recessiveallele (1) promotes the expression of kernel color when homozygous. Another dominant allele, (P),causes purple kernel color, while the homozygous recessive genotype (pp) causes red kernels.Assuming that these alleles assort independently, predict the phenotypic ratio of the offspring iftwo plants dihybrid for these characteristics are crossed.

Alleles are the alternative forms of a gene that are located on the same locus of a homologous…

Answered: In corn plants, a dominant allele (1)…

In c. elegans, genetics model organism, movement problems (unc) and small body size (sma) are encoded by two mutant alleles that are recessive to those that produce wild-type traits (unc+ and sma+). A worm homozygous for movement problems and small body is crossed with a worm homozygous for the wild-type traits. The F1 have normal movement and normal body size. The F1 are then crossed with worms that have movement problems and small body size in a testcross. The progeny of this testcross is: Normal movement, normal body size 210 Movement problems, normal body size 9 Normal movement, small body size 11 Movement problems, small body size 193 a)From the test cross results, can you tell if the two genes are on the same chromosome or not? Explain your reasoning. b)What phenotypic proportions would be expected if the genes for round eyes and white body were located on different chromosomes? (please explain hot to get to these conclusions)
Explain the possible reasons for the observed differences in the sample means. Account for the differences in the sample means of P1 and P2. Similarly, account for the differences in the sample means of the F1 and F2. Compare the difference in the parental generations with that in the filial generations.
A pea plant believed to be heterozygous was selfed and produced pods with the followingphenotypes: 26 constricted yellow73 constricted green83 inflated yellow251 inflated green a. Using the letters A and B, assign alleles to the different traits.b. Determine whether the ratio of pea pods support the hypothesis that the plant isheterozygous.
Let us suppose that two plants are crossed (mated). One plant (female) is homozygous dominant and produces chlorophyll, and the other (male) is homozygous recessive and does not produce chlorophyll. These two plants are considered the parental, or P generation. What would be the possible genotypes and phenotypes of these two individuals? Fill in the table below with the parental generation's descriptional information. Table 6.1 Female Male Description Parental Generation Homozygous dominant P Generation Genotype gg Phenotype Green

Y = yellow, y = green; R = round seed, r = wrinkled seed %3D An individual has the genotype YYRR and has offspring with an individual with the genotype yyrr.

In peas, tallness is dominant over dwarfness, and red colour of flowers is dominant over the white colour. When a tall plant bearing red flowers was pollinated by a dwarf plant bearing white flowers, the different phenotypic groups were obtained in the progeny in numbers mentioned against them. Tall, Red = 138 Tall, White = 132 Dwarf, Red = 136 Dwarf, White = 128 %3D Mention the genotypes of the two parents and of the types of four offspring.
Calculate the map distances between the genes.
If an allotetraploid species is made up of two ancestral genomes, A and B, with each of them having a basic chromosome number of seven. The resistance to the pathogen attacking the foliage of plants is controlled by a dominant allele located at the F locus. The recessive alleles F^a and F^b show sensitivity to the pathogen. Plants with at least on F^A allele are resistant to the pathotype 1 and 2 (regardless of the genotype in B genome), and plants with at least one F^B allele are resistant to pathotypes 1 and 3 (regardless of genotype in A genome). What proprtion of the self-progeny of F^AF^a F^BF^b plant will be resistant to pathotype 1, 2 and 3?
