Assuming simple dominance, what will be the result of a cross between P1 generation true-breeding lines of purple and white sea slugs? mostly purple sea slugs in the F1 generation, with an occasional white sea slug all purple sea slugs in the F1 generation, but a lighter purple than in the parents all white sea slugs in the F1 generation all purple sea slugs in the F1 generation

Suppose that in plants, smooth seeds (S) are dominant to wrinkled seeds (s) and tall plants (T) are dominant to short plants (t). A tall plant with smooth seeds was backcrossed to a parent that was short and wrinkled. What proportion of the progeny is expected to be heterozygous for tall and smooth?
Carrion beetles lay their eggs in dead animals and then bury them in the ground until they hatch. Assume that the preference for fresh meat (F) is dominant to the preference for rotted meat and that the tendency to bury the meat shallow (S) is dominant to the tendency to bury the meat deep. Suppose a female carrion beetle homozygous dominant for both traits mates with a male homozygous recessive for both tra What will be the genotype of the F1 generation?
More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. 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. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c. Parents: brown eyes, right-handed blue eyes, left-handed Offspring: 1/4 brown eyes, right-handed 1/4 brown eyes, left-handed 1/4 blue eyes, right-handed 1/4 blue eyes, left-handed
If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of? a. dominance b. codominance c. multiple alleles d. incomplete dominance
In Elves, curled toes (T) is dominant to flat toes (t). If an Elf that is heterozygous were crossed with an Elf that is homozygous recessive, what possible offspring could there be in the F1 generation?
In fruit flies, the allele for normal wings (V) is dominant to the allele for short wings (v). Suppose two fruit flies heterozygous for the trait are mated. What is the male fruit fly’s genotype and the female fruit fly’s genotype? What is the male fruit fly’s phenotype and the female fruit fly’s phenotype? What will be the genotypic ratio of the F1 generation? What will be the phenotypic ration of the F1 generation?
The trait of feathering in fowls is a sex-limited trait controlled bya single gene. Females always exhibit hen-feathering, as do HHand Hh males. Only hh males show cock-feathering. Startingwith two heterozygous birds that are hen-feathered, explain howyou would obtain a true-breeding line that always produced cockfeathered males.
With regard to heterosis, is each of the following statements consistent with the dominance hypothesis, the overdominance hypothesis, or both? A. Strains that have been highly inbred have become monomorphicfor one or more recessive alleles that are somewhat detrimentalto the organism. B. Hybrid vigor occurs because highly inbred strains are monomorphicfor many genes, whereas hybrids are more likely to beheterozygous for those same genes.C. If a gene exists in two alleles, hybrids are more vigorousbecause heterozygosity for the gene is more beneficial thanhomozygosity of either allele.

Suppose that a gene affects the anterior morphology in house flies andis inherited as a maternal effect gene. The gene exists in a functionalallele, H, and a recessive nonfunctional allele, h, which causes a smallhead. A female fly with a normal head is mated to a true-breedingmale with a small head. All of the offspring have small heads. Whatare the genotypes of the mother and offspring? Explain your answer
Woodrats are medium sized rodents with lots of interesting behaviors. You may know of them as packrats. Let's assume that the trait of bringing home shiny objects (H) is controlled by a single locus gene and is dominant to the trait of carrying home only dull objects (h). Suppose two heterozygous individuals are crossed. How many of each genotype would be expected if only 4 offspring were produced? How many of each phenotype would be expected?
