In rabbits, chocolate-colored fur is dominant to white fur (w), straight fur is dominant to curly...
In rabbits, chocolate-colored fur (w +) is dominant to white fur, straight fur (c +) is dominant to curly fur (c), and long ear (s +) is dominant to short ear (s). The cross of a trihybrid rabbit with straight, chocolate-colored fur and long ears to a rabbit that has white, curly fur and short ears produces the results in the table. a. Determine the order of the genes on the chromosome. b. Identify the alleles that are present on...
in Rabbits the dominant allole ® Laulle black fur & the recessive, allele causes brown fur (b). For an independently Assorting gene the dominant allite (R causis long hair and cances Short hair. A heterozygous rabbit w/ long black fur Is Grossed w/ a short brown fur rabbit, what proportion of the offspring will be heterozigous for at least one
QUESTION 1 Both of Molly’s parents have curly hair but Molly has straight hair, explain how you could use a Punnett square to illustrate how this is possible. Lali Estimate the phenotypes of potential offspring: 75% having brown fur and 25% of the offspring having white fur. Exercise 1: Understanding Alleles The chart below identifies the relationship between genotype and phenotype. You will use this chart to determine the characteristics of a puppy. Note: for simplicity all of the traits...
1. (4pts) In a strain of rabbits, the allele E (long ear) at the locus for ear length is dominant over the allele e (short ear). The spotted coat allele (s) is recessive when tested against the solid colored coat allele (S). One long eared, solid colored male rabbit is bred to three females. Female A, which has short ears and spotted coat, produces two long eared, solid colored offspring, and one short eared, solid colored offspring, Female B, which...
6. In tigers, a dominant allele (W) is responsible for the expression of the normal orange pigment. Individuals that inherit twe recessive alleles (w) lack the normal orange pigment in their fur, appearing white with black stripes. A pair of normally colored parewis produces a cub that is white with black stripes and scab that is orange with black stripes. What are the possible genotypes of the cube? b. What are the possible genotypes of the parents? 6. Explain your...
Biol 189 0. Allele "l' is a recessive allele that results in short cars in rabbits, while 'L' is the dominant, long ear allele. a) What gametes would be produced by a heterozygote? 6 bunicat36690OS 0 1261 b) Assuming complete dominance, what fraction of offspring would have short ears if you crossed a heterozygous rabbit with a homozygous recessive rabbit? SSSS 1802 403 Ri p osa bence c) What are the phenotype ratios of the offspring in a cross between...
5. You started working in a Drospohila lab. You are studying two different autosomal traits, body color and antennae length. Gray body (B) is completely dominant to black body (b) and long antennae length (A) is completely dominant to short antennae length (a). You cross true-breeding gray bodied, long antennae files to true-breeding black bodied, short antennae. The F1 progeny all have gray bodies and long antennae. a. You perform a testcross to the F1 progeny produced from the parent...

2. A dominant allele H reduces the number of body bristles that Drosophila flies have, giving rise to a “hairless” phenotype. In the homozygous condition, H is lethal. An independently assorting dominant allele S has no effect on bristle number except in the presence of H, in which case a single dose of S suppresses the hairless phenotype, thus restoring the "hairy" phenotype. However, S also is lethal in the homozygous (S/S) condition. What ratio of hairy to hairless flies...
