Suppose the ear length of two populations of jerboas is controlled by one gene. To determine the mode of inheritance, a homozygous short-eared female is crossed with a homozygous long-eared male. Then, siblings from the F₁ are crossed, and the number of short- and long-eared animals are counted to determine the phenotype ratio. Match the phenotypic ratio anticipated in the offspring from a cross of two heterozygous individuals to the appropriate mode of inheritance for the short-ear allele.

In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?
Is this pedigree consistent with extranuclear inheritance of the shaded characteristic? Select one: a. Yes O b. No
Suppose in a strain of soybeans, high oil (H) content in the seeds is dominant to low oil content and four seeds (E) in a pod is dominant to two seeds in a pod. A farmer crosses two soybean plants, both with high oil content and four seeds per pod. The resulting F1 offspring have a phenotypic ratio of 9:3:3:1 (High oil/four seeds: High oil/ two seeds: Low oil / four seeds : Low oil / two seeds). What genotype were the parent plants?
In a species of tropical fish, a colorful orange andblack variety called montezuma occurs. When twomontezumas are crossed, 2/3 of the progeny are montezuma and 1/3 are the wild-type, dark grayish greencolor. Montezuma is a single-gene trait, and montezuma fish are never true-breeding.a. Explain the inheritance pattern seen here and showhow your explanation accounts for the phenotypicratios given.b. In this same species, the morphology of the dorsalfin is altered from normal to ruffled by homozygosity for a recessive allele designated f. What progenywould you expect to obtain, and in what proportions, from the cross of a montezuma fish homozygous for normal fins to a green, ruffled fish?c. What phenotypic ratios of progeny would be expected from the crossing of two of the montezumaprogeny from part (b)?
Use a punnett square in fruit flies, red eyes (r) are dominant to pink eyes (r). what is the phenotypic ratio of a cross between a heterozygous male and a pink-eyed female
In oats, the color of the chaff is determined by a two-gene interaction. When a true-breeding black chaff plant was crossed to a truebreeding white chaff plant, the F1 generation was composed of allblack chaff plants. When the F1 offspring were crossed to eachother, the ratio produced was 12 black to 3 gray to 1 white. First,construct a Punnett square that accounts for this pattern of inheritance. Which genotypes produce the gray chaff phenotype? Second,at the level of protein function, how would you explain this type ofinheritance?
Using Punnett Squares to Understand Inheritance Scenario 2: A truebreeding brown mouse is repeatedly mated with a true-breeding tan mouse, and all their offspring are tan. What would be the genotypic ratio of the F2 generation? O 1:3 O 2:1:1 O 3:1 1:2:1

In rabbits, white coat color (CW) and black coat color (CB) are codominant, and both of these alleles are dominant over albino (c); heterozygotes (CWCB) are spotted. Predict the genotypes and phenotypes of the offspring from a heterozygous black-coated rabbit and a homozygous white-coated rabbit.

In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a.
