Homozygous and Heterozygous

1. What is the Difference between Homozygous and hHterozygous?

Answer:

Human have two set of chromosomes and when an individual has two identical alleles for a particular gene (e.g., AA or aa)it is known as homozygous and when an individual which has two different alleles for a specific gene (e.g., Aa) it is known as heterozyous.

2. What is the Significance of Homozygosity in Genetics?

Answer:

Homozygous individuals express the trait linked with the single allele they carry , which can be helpful in determining the dominance or recessiveness of a particular allele.

3. How does Heterozygosity contribute to Genetic Diversity?

Answer:

Heterozygosity results in genetic diversity by introducing different alleles within a population and this diversity is important for adaptation and evolutionof the species.

4. How do Homozygous and Heterozygous Traits relate to Mendelian genetics?

Answer:

Mendelian genetics studies the inheritance of traits, and homozygous and heterozygous conditions help explain how traits are passed from one generation to the next according to Mendel’s laws.

5. How does the Concept of Codominance relate to Homozygous and Heterozygous conditions?

Answer:

Codominance occurs when both alleles in a heterozygous individual are fully expressed. It contrasts with incomplete dominance, where the heterozygous condition results in an intermediate phenotype.

Homozygous and heterozygous are terms used in genetics to describe the types of alleles an individual possesses for a particular gene. A homozygous individual carries two identical alleles(RR or rr) for a specific gene while a heterozygous individual carries two different alleles(Rr) for a specific gene. The concepts of homozygous and heterozygous genotypes are fundamental in explaining the inheritance patterns of traits as described by Gregor Mendel.
