Explore the full setWhat is heredity and how does it occur in humans?
Answer
Heredity is the passing down of characters from parents to offspring through genes. It occurs when genetic information stored in DNA is transferred from parent cells to offspring during reproduction.
A child has free earlobes while both parents have attached earlobes. How is this possible?
Answer
This is impossible if free earlobes are dominant and attached earlobes are recessive. Both parents with attached earlobes (recessive) can only pass recessive genes to their child, who would also have …
Why is Gregor Mendel called the 'Father of Genetics'?
Answer
Mendel was the first scientist to systematically study inheritance patterns using pea plants. He discovered fundamental laws of heredity by conducting controlled experiments over many years, analyzing…
What are Mendel's two main laws of inheritance?
Answer
1st Law (Law of Segregation): Each trait is controlled by a pair of factors that separate during gamete formation. 2nd Law (Law of Dominance): One factor (dominant) may express despite the presence of…
A tall plant (TT) is crossed with a dwarf plant (tt). What will be the height of F1 offspring?
Answer
All F1 offspring will be tall (Tt). Since tallness (T) is dominant over dwarfness (t), the dominant gene expresses even in the presence of the recessive gene. The F1 generation shows 100% tall plants …
What are chromosomes and where are they located?
Answer
Chromosomes are thread-like structures located in the cell nucleus. Each chromosome contains one DNA molecule and proteins. Humans have 46 chromosomes (23 pairs) - 22 pairs of autosomes and 1 pair of …
How do human cells maintain 46 chromosomes during cell division?
Answer
Before cell division, DNA replication occurs. Each chromosome duplicates to form two identical chromatids joined at the centromere. During division, chromatids separate and move to different daughter …
What are the three main steps of DNA replication?
Answer
1. Unwinding: The double-stranded DNA unwinds with help of enzymes to expose two strands. 2. Synthesis: DNA polymerase enzyme forms new daughter strands complementary to each parent strand. 3. Formati…
