5 Questions
Explain co-dominance in genetics.
Co-dominance involves both alleles being expressed simultaneously, neither dominant nor recessive.
What happens when alleles CR and CW are present in snapdragon flowers?
Pink flowers result when both alleles CR (red pigment) and CW (white pigment) are present.
How are punnett squares used to illustrate co-dominance inheritance?
Punnett squares are used to show crosses between pure breeding red and white plants, resulting in pink flowers and rowan cattle.
What is the importance of presenting answers in a specific format for co-dominance inheritance in exams?
Presenting answers in a specific format covers four key points for maximum marks in exams.
Give an example of a co-dominance scenario in genetics.
An example of co-dominance is the snapdragon flower alleles CR and CW resulting in pink flowers.
Study Notes
- Session focuses on co-dominance inheritance in biology.
- Co-dominance involves both alleles being expressed simultaneously, neither dominant nor recessive.
- Example given with snapdragon flowers: alleles CR (red pigment) and CW (white pigment) result in pink flowers when both are present.
- Examples of punnett squares shown for crosses between pure breeding red and white plants, resulting in pink flowers and rowan cattle.
- Emphasis on presenting answers in a specific format covering four key points for maximum marks in exams.
Explore co-dominance inheritance in biology with a focus on alleles being expressed simultaneously without dominance or recessiveness. Learn about the example of snapdragon flowers displaying pink color due to the presence of both red and white pigment alleles. Practice punnett squares for crosses between pure breeding plants to understand inheritance patterns.
