In humans the brown eye allele is dominant to the blue eyes allele if two heterozygotes mate what will be the likely genotype and phenotype ratios of the offspring

In frost moths, two alleles of one gene determine the character difference of spotted versus striped wings and two alleles of a separate, independent gene determine the character difference of orange wing background versus white wing background. The results for four matings of moth phenotypes are shown below.     Number of progeny Mating Parental Phenotypes Spotted/orange Spotted/white Striped /orange Striped  /white 1 spotted/orange x striped/orange 623 0 637 0 2 spotted/white x striped/orange 0 0 0 712 3 spotted/white x striped/orange 122 131 128 133 4 spotted/orange x striped/white 0 0 430 422 striped= S(dominant) spotted=s (recessive) white= W(dominant) orange=w (recessive)   What are the genotypes of each parent in each cross?  If more than one genotype is possible, list the alternative possibilities.  (Remember that each mating involves a separate set of parents, so the 4 matings involve 8 separate…

In dogs, the color black is dependent upon the dominant allele B and white upon the recessive allele b. If two heterozygous black dogs mate, what genotypes and phenotypes may show up in the F1 generation?

In the species Chinchilla chinchilla, Neotropical crepuscular rodent of the parvorder Caviomorpha, a mating between a homozygous long-tailed chinchilla male and a homozygous short chinchilla female will produce all medium length tail chinchilla offspring. When these medium length tail chinchilla offspring F₁ are mated, their offspring consists of 3 tail-less chinchillas, 24 long-tailed chinchillas, 120 medium-length tailed chinchillas, and 15 short-tailed chinchillas. What genetic interaction may be occurring in this population? Please explain

With a genotype of the parents of YYRR x YyRr, what is the percent probability of offspring having a genotype of Yyrr? 75% 50% 25% 0%

In fruit flies, the red allele is dominant to the allele for sepia eyes. In a certain population of 1000 fruit flies, 640 flies have red eyes while the remainder have sepia eyes. How many individuals would you expect to be homozygous dominant for red eye color?

Roan cattle show codomiance for the color of their hair. There are allele for red hair and white hair what would you expect a heterozygous roan bull to look like if the trait showed incomplete dominance instead

What would the genotypes and genotypic ratio be for the F2 generation produced in a phenotype and phenotypic ration of F1 individuals that were produced from a male blue tailed gecko crossed with a female green tailed gecko, being that all 28 of the offspring had green tails, were mated brother and sister?
