a.

Summary Introduction

To determine: The possible phenotypes for the co-dominant alleles a, b, c, and recessive allele d.

Introduction: The genotype is the genetic constitution of the organism whereas the phenotype refers to external characters visible in an organism. The alleles are the contrasting forms of a gene, and one of them is dominant, and the other is recessive.

b.

Summary Introduction

To determine: The possible genotypes for the co-dominant alleles a, b, c, and recessive allele d.

Introduction: The dominant allele masks the expression of the recessive allele. Therefore, the dominant allele is expressed in homozygous and heterozygous genotypes whereas the recessive phenotype is only expressed under homozygous condition.

Name ENRICHMENT ACTIVITY (continued) Genetics Problem Solving Crosses Involving Multiple Alleles 25 Step 4 Combine the gamete genotypes of one parent with those of the other parent to show all possible offspring genotypes. 14 JAJA I^i |8 [+18 1Bi Step 5 State the genotype and phenotype ratios of the offspring. 1 : 1 Pi: 1118: 118 = 141, 141, 148, 1418 2 type A: 1 type AB: 1 type B = 1/2 type A, 14 type AB, 4 type B CHAPTER EXERCISES For each exercise draw the Punnett square when appropriate and answer the questions in the spaces provided. 1. A woman homozygous for type B blood marries a man who is heterozygous type A. What will be the possible genotypes and phenotypes of their children? 2. A man with type O blood marries a woman with type AB blood. What will be the possible genotypes and phenotypes of their children? 3. A type B woman whose mother was type O marries a type O man. What will be the possible genotypes and phenotypes of their children? 4. A type A woman whose father was…
Mendelian Genetics Hermione's parents are muggles (cannot perform magic). How is it possible for Hermione to do magic? What are the genotypes of her parents? Is the ability to perform magic dominant or recessive? Hagrid is a half-giant. If his father was a giant, what is the phenotype of his mother? Which trait is dominant?
Mendelian Genetics Punnett Square Question :  In cattle, the hornless condition (H) is dominant to that for the possession of horns (h). a) A horned bull is mated to a hornless cow which is heterozygous . What kind of offspring are to be expected and in what ratio ? b) If the cow is then mated to a hornless bull which is also heterozygous, what is the chance that the first calf will have horns ? c) Assuming that the first calf has horns, what is the chance that the second calf will be hornless ?
