Hi, can you help me solve this monohybrid cross? (Most especially on letter B). Thank you.
1. In humans, achondroplasia “dwarfism” is dominant over normal. A homozygous dominant person dies before the age of one. A heterozygous person is dwarfed. A homozygous recessive individual is normal. A heterozygous dwarf man marries a dwarf heterozygous woman.
a. What is the probability (in percent) of a having a normal child?
b. What is the probability (in percent) that the next child will also be normal?
c. What is the probability (in percent) of having a child that is a dwarf?
d. What is the probability (in percent) of having a child that dies at one from this disorder?
