Two dogs who carry the gene for deafness but have normal hearing are mated. What are the possible genotypes and phenotypes of their offspring and the percent chance for each? D D Fill in the table: Genotype Phenotype Chance In guinea pigs, short hair is dominant over long hair. If a short haired SS guinea pig is crossed with a long haired ss guinea pig, what are the possible genotypes and phenotypes of their offspring and the percent 3.
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?
In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?
In dogs, a dominant gene (1) determines white coat, and a recessive gene (i) gives colored coat. In the presence of ii the coat color is black due to the dominant gene B, or brown due to the recessive gene b. Two dogs both having the Bbli genotype were mated. Answer the following questions and show complete solutions to support your answers. Use the branching method whenever applicable. What is the phenotypic ratio of the offspring? What type of gene interaction is exhibited by the coat color in dogs? What would be the probability of getting dogs that are pure-breeding for a black coat color? 3. a. b. C.

In cats, the locus for orange coat color is sex linked. Male cats that are black have the o+ allele, whereas those that are orange have the o allele. Females can be homozygous for the orange allele or homozygous for the black allele and will express each color, respectively. Heterozygous females are tortoise-shelled or calico, having orange and black patches. A calico cat, in addition to being heterozygous at the orange locus, also is either heterozygous or homozygous for the incompletely dominant, autosomal spotting allele (SS = large spots, Ss = small spots, ss = no spots). Manx tails are caused by a dominant trait that is lethal when homozygous. Long tails are the result of a homozygous recessive genotype. An orange male with small white spots and a manx tail is crossed to a calico female with small white spots and a manx tail. What is the probability of observing a solid black female with no spots and long tail? (Hint: All calico cats are female!)
In dogs, wire-haired is due to a dominant gene (W), smooth-haired is due to its recessive allele (w). (must show Punnett Square) Two wire-haired dogs are mated. Among the offspring of their first litter is a smooth-haired pup. What is the Genotype of the Parents? () If these, two wire-haired dogs mate again, what are the chances that they will produce another smooth-haired pup? What are the chances that the pup will wire-haired pup? (+) A wire-haired male is mated with a smooth- haired female. The mother of the wire-haired male was smooth-haired. What are the phenotypes and genotypes of the pups they could produce? (t)
*Genetics Matt observed 80 green frogs and 20 brown frogs. He knows from published studies, brazilian frog coloration derives from two alleles (p=green and q=brown). After genotyping the green frogs he finds they are homozygous for the p allele. What percentage of heterozygous frogs should he expect to find?
Black coat colour in cocker Spaniels is governed by a dominant allele B and red coat colour by its recessive allele b; solid pattern is governed by the dominant allele of an independently assorting locus S, and sported pattern by its recessive allele s. A solid black male is mated to a solid red female and produces a litter of six pups: two solid black, two solid red, one black and white, and one red and white. (a) What are the possible genotypes of all the phenotypes obtainable? (b) Determine genotype of the parents. Hint- an unknown portion of a genotype may be indicated by a dash (-).
In mice, tail shape (bent vs. straight) is controlled by alleles of one gene. You cross a mouse with a bent tail to a mouse with a straight tail. Half of the offspring have bent tails, half have straight tails (regardless of sex). What can you conclude? O Both mice are homozygous Bent is dominant to straight Both mice are heterozygous O One mouse is heterozygous, the other is homozygous O Straight is dominant to Bent
In fruit flies and humans, sex is determined by an X-Y system. However, many organisms do not have the X-Y system of sex determination just like in birds. Instead, they have the Z-W system. Male birds are ZZ whereas, female birds are ZW. In chickens, barred feathers (ZB) are dominant over nonbarred feathers (Zb). If a barred female chicken mates a nonbarred male chicken, what is the probability of having barred female offspring? 50% 0% 25% 100%
