When you are visiting the local pet store you start talking to them about their Ceti alpha-5 eel colony. They tell you that some eels have red antennas, some have white antennas, and some have pink antennae. Whenever you cross an eel with red antennae to an eel with white antennae you only recover eels with pink antennae. If you assume antennae color is under the control of one gene and you cross two eels with pink antennae what would you predict would be the genotypes and phenotypes of the progeny? How would you explain these results? (Describe why the expected results from ‘a’ would happen.)
The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion.
You are looking at the color of feathers in ducks and find that yellow ducks (Y) are dominant to green ducks (y). However, a second gene, H, controls whether the color will be expressed in the feathers. If the duck is hh, the duck will always be white, because the pigment does not go into feathers. What ratio of phenotypes would you expect following a dihybrid cross? A) 9:6:1 B) 9:3:4 C) 13:3 D) 15:1 E) 12:3:1
Gene mapping is often used to predict genetic traits that can be passed on, but what exactly does it map? A. Genes on a chromosome B.Genes in the brain C. Genes in the cell D. Genes in the nucleus

In humans, a dimple in the chin is a dominant characteristic controlled by a single gene.a. A man who does not have a chin dimple haschildren with a woman with a chin dimple whose mother lacked the dimple. What proportion of theirchildren would be expected to have a chin dimple?b. A man with a chin dimple and a woman who lacksthe dimple produce a child who lacks a dimple.What is the man’s genotype?c. A man with a chin dimple and a nondimpledwoman produce eight children, all having the chindimple. Can you be certain of the man’s genotype?Why or why not? What genotype is more likely,and why?
Fruit flies are very useful model organisms that have been used to study genetics. One mutant recessive trait in fruit flies is called "eyeless" because it causes flies to have no eyes. Cross an eyeless fly with a homozygous normal fly. a. Draw the Punnett square. b. What is the genotyoe ratio of the offspring? c. What is the phenotype ratio of the offspring? d. What genetic problem is this? (monohybrid, dihybrid or multiple allele)
In sheep, coat color is influenced by two genes. Gene A influences pigment production, while gene B produces black or brown pigment. If two heterozygous white sheep resulted in 12 white sheep, 3 black sheep, and 1 brown sheep, which genotype(s) of the white sheep explain this data? A) The white sheep could be A-B- or aaB-. B) The white sheep could be A_B_ or aabb. C) The white sheep could be A_B_ or A_bb. D) The white sheep must all be aabb. E) The white sheep must all be A_B_.
A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower From the cross (P1) RrDdccOoHhWw x (P2) RrddCcooHhww, determine: Note: RrDdccOoHhWw is one genotype. a. How many kinds of gametes can be formed by P1?b. How many genotypes are possible among the progeny of this cross?c. How many phenotypes are possible among the progeny?d. What is the probability of obtaining the RrDdccOohhww genotype in the progeny?e. What is the probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny?
Imagine that you are performing a cross involving seed color in garden pea plants. What traits would you expect to observe in the F1 offspring if you cross true-breeding parents with green seeds and yellow seeds? Yellow seed color is dominant over green. a. only yellow-green seeds b. only yellow seeds c. 1:1 yellow seeds:green seeds d. 1:3 green seeds:yellow seeds
Genes A and B are 6 map units apart, and A and C are 4 map units apart. Which gene is in the middle if B and C are 10 map units apart? Which is in the middle if B and C are 2 map units apart?
What was the hypothesis of the X-linked cross conducted in the lab (between white-eyed female and re-eyed male) with the white mutation in Drosophila and written up in your lab report? A All female offspring will inherit red eyes from their mother because the mutation is X linked recessi B All female offspring will inherit white eyes from their mother because the mutation is X linked recessive. C All male offspring will inherit white eyes from their mother because the mutation is X linked recessive. D All male offspring will inherit red eyes from their mother because the mutation is X linked recessive. E All male offspring will inherit white eyes from their mother because the mutation is X linked dominant.
