Chapter 14, Problem 12TYKM
Summary Introduction
To match: The monohybrid cross with its description.
Introduction: Gregor Johann Mendel is known as “Father of modern genetics”. Genetics is the branch of biology that deals with the study of genes, their inheritance patterns, factors that control them, structure, and function.

. A man with a blood type AB is married to a woman with blood type A. They have natural children and one adopted child. These are the children with their blood type: Baltazar has blood type A, Melchor has blood type AB and Melchor has blood type O.
a. Who was adopted?
b. What genetic problem is this? (monohybrid, dihybrid or multiple allele)
c. Show the Punnett square.
Having dimples (D) is dominant over not having dimples (d). A dimpled woman (whose father had no dimples and whose mother did have dimples) marries a man whose mother had no dimples, whose father had no dimples, and whose grandparents on his father’s side did have dimples!
a)What are the genotypes of the man and woman?
b) Show the cross.
c)How many different genotypes are possible among the offspring?
d)How many different phenotypes are possible among the offspring?
e)What is the probability of getting DD offspring?
f) What is the probability of getting dd offspring?
g) What is the probability of getting dimpled offspring?
h) What is the probability of getting offspring with no dimples?
i)What is the probability of getting homozygous offspring?
Imagine a test cross for an unknown exhibiting 2 traits, where half of the offspring exhibit both dominant traits and the other half exhibits one dominant and one recessive trait. What can you conclude about the unknown?
options:
A) The unknown is homozygous dominant for both traits.
B) The unknown is homozygous recessive for both traits.
C) The unknown is heterozygous for both traits.
D) The unknown is homozygous for one gene and heterozygous for the other.
E) There is not enough information to determine the answer.
