Homework Answers
Option 2nd is the correct answer. In case of codominance, both characters are equally expressed.
Option 1st is correct because in case where red is dominant over white, the calf will have either red only or white only.
Option 3rd is not correct because in case of incomplete dominance, both characters blend and produce an intermediate phenotype.
Option 4th is not correct because the characters are not related with gender.
Option 5th is not correct because in case of pleiotropy, presence of one gene affects the effect of other genes.

Clownfish exhibit three phenotypeni red, yellow, and orange. If a red clownfish is mated with a yellow clownfish, the resulting progeny are all orange. a. What type of inheritance pattern do you suspect? incomplete dominance b. Construct a Punnett square to illustrate a cross between two RRRR orange clownfish. (make up letters to represent the alleles) 15. RRR Genotypic ratio: la: Phenotypic ratio: 1: 2!! There are 4 alleles (C.ch, ch, and e) of the gene for coat...

7. A red snapdragon flower is crossed with a white snapdragon flower. All of the offspring are pink snapdragon flowers. You study the pink snapdragon flowers and discover that these flowers produce red pigment but at low levels, thus causing the pink color. What type of genetic inheritance is this? What is the genotype of the red snapdragon flower? What is the genotype of the white snapdragon flower? What is the genotype of the pink snapdragon flower? You cross a...

18. Coat color in shorthorn cattle is determined by incomplete dominance. Individuals homozygous for the red allele (CRC) have red fur, individuals homozygous for the white allele (CWCW) have white fur, and heterozygous individuals (CCW) are roan (brown and white). A second gene in these cattle determines if they will have horns. The horned allele (H) is dominant to hornless (h). Predict the genotypic and phenotypic ratios of the offspring if a heterozygous horned-roan bullis crossed with a hornless -...

1. Genetically identical plants are planted in a garden. Ones on the east edge of the garden produce blue flowers; the others produce pink flowers. How can this best be explained? environmental factors influence flower color the alleles are codominant the allele for blue flowers is dominant a mutation must have occurred multiple alleles affect flower color 2. In a species of mammal, some individuals are true-breeding for red hair. Others are true-breeding for brown hair. A true-breeding red individual...
