Each of two parents has the genotype brown divided by blond​, which consists of the pair of alleles that determine hair color​, and each parent contributes one of those alleles to a child. assume that if the child has at least one brown ​allele, that color will dominate and the​ child's hair color will be brown.
a. list the different possible outcomes. assume that these outcomes are equally likely.
b. what is the probability that a child of these parents will have the blond divided by blond ​genotype?
c. what is the probability that the child will have brown hair color​?

Mendelian, monogenic or monofactorial heredity is used to characterize disease transmission due to a mutation in a single gene. This mode of transmission follows the laws of Mendel, which explains the use of the term "Mendelian".It is inherited by syngamy and then karyogamy of maternal and paternal genomes at the time of fertilization.
1. The different possible outcomes are:
The parents:  MB MB
The children:  MM   Mb   Mb   b

2. The probability that a child of these parents will have the blond divided by blond genotype:
MM  Mb  Mb  bb   ==> 2/4 ==> 50%

3. The probability that the child will have brown hair color:
MM  MB  MB  BB   ==> 3/4 ==> 75%
