Genetics and Heredity Quiz

Key Figures in Inheritance

• Gregor Mendel is recognized as the first scientist to effectively apply quantitative methods to the study of inheritance.

Understanding Sex-Influenced Traits

• Sex-influenced traits are characteristics where the expression is influenced by the sex of an individual, often differing between males and females.

Tissue Types

• There are four main types of tissues in the human body: epithelial, connective, muscle, and nervous tissues.

Modern Inheritance Studies

• The study of inheritance as a modern scientific discipline was initiated in the mid-19th century, marked by Mendel’s work.

Gender and Recessive Alleles

• In humans, a female requires two recessive alleles to express a sex-influenced trait, as they need one from each parent.

Conservation Threats

• Habitat destruction is the main direct threat to conservation and a significant cause of biodiversity loss.

Biodiversity Decline Factors

• Numerous scientists and the IPBES Global Assessment Report identify habitat loss as the primary factor in the decline of biodiversity.

Biological Diversity Loss

• The phenomenon of extinction can lead to a temporary or permanent loss of biological diversity.

Global Extinction Rate

• The current global extinction rate, often termed the "sixth mass extinction," reflects unprecedented biodiversity challenges.

Categories of Conservation Threats

• Various categories include habitat destruction, pollution, climate change, and invasive species, all recognized as threats to conservation and contributors to biodiversity loss.
