In eggplants, the gene for smooth fruit is dominant over the gene for hairy fruit.

5. What two possible genotypes could represent a smooth fruit phenotype?

a. SS or Ss

b. HH or Hh

c. Sh or hh

d. ss or hh

6. What is the genotype of a hairy fruited eggplant?

a. SH

b. HH

c. hh

d. ss

Using the information from # 5 & 6, cross a heterozygous plant with a homozygous recessive plant.

7. The phenotype ratio of the offspring is            

  1. 1:1
  2. 3:1
  3. 1:2:1
  4. 2:2 or 1:1

8. The genotype ratio of the offspring is _____________

  1. 1:1
  2. 3:1
  3. 1:2:1
  4. 2:2 or 1:1

The HAIR gene (abbreviated as H) controls hair color with the dominant phenotype being dark brown hair and the recessive phenotype being blonde hair. The WIDOW gene (abbreviated as W) controls the presence of a ‘widows peak’ in the hairline (having a point at the center of the hairline). Having a widows peak is dominant and not having a widows peak is recessive. Gene H and Gene W are linked genes. Two individuals with the genotypes indicated below mate (note:...

Recitation 5 short-answer assignment You are investigating two traits in fruit flies controlled by one gene each. The b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). After crossing rugose black flies with smooth brown flies, you obtain an F1 generation of 100% smooth black flies. What are the dominant alleles? (1 pt) What are the genotypes of the two parent flies to perform a dihybrid test cross? (1...

In guinea pigs, rough coat (R) is dominant over smooth coat (r) and black (B) is dominant over white (b). R and B are independent genes. Cross a homozygous rough black animal with a smooth white one. What are the genotypes and phenotypes of the offspring? Choose any two offspring and cross them, determining the genotypes and phenotypes of the next generation.
