Biology Question on Principles of Inheritance and Variation
A condition where a certain gene is present in only a single copy in a diploid cell is called.
A
Monogamous
B
Heterozygous
C
Hemizygous
D
Homozygous
Answer
Hemizygous
Explanation
Solution
- Monogamous: Monogamous species are characterized by individuals having only one lifelong partner or mate.
- Heterozygous: A heterozygous individual, in the context of diploid organisms, possesses two alleles, each of a distinct type.
- Hemizygous: Hemizygous refers to a genetic state wherein a gene or allele exists in only one copy within a diploid cell, as observed in human males.
- Homozygous: Homozygous denotes a genetic state where an individual carries two identical copies of genes.
So, the correct option is (C): Hemizygous.
