The study of heredity began with Mendel who is known as the "Father of Genetics." He discovered that traits are inherited through factors we call alleles, which are different forms of a gene. The genetic makeup of an organism, called its genotype, determines its physical traits, or phenotype. When an organism has two identical alleles for a trait, it is described as homozygous. If it has two different alleles, it is heterozygous. Some traits are controlled by dominant alleles, which overshadow recessive alleles in heterozygous individuals. Some traits show codominance such as a cow with both red and white hair appearing as patches, where both alleles are fully expressed. In contrast, incomplete dominance results in a blend of traits, like a pink flower produced from a red and white flower cross.
Fill in the blanks with the correct answer
The study of heredity began with Blank
who is known as the "Father of Genetics." He discovered that traits are inherited through factors we call blank, which are different forms of a gene. The genetic makeup of an organism, called its blank,
determines its physical
traits, or blank.
When an organism has two identical alleles for a trait, it is described as blank.
If it has two different alleles, it is blank.
Some traits are controlled by blank
alleles, which overshadow blank
alleles in heterozygous individuals. Some traits show blank
such as a cow with both red and white hair appearing as patches, where both alleles are fully expressed. In contrast, blank
results in a blend of traits, like a pink flower produced from a red and white flower cross.
