Genetic Inheritance Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What are gametes and where are they found in animals and plants?

Gametes are sex cells.

In animals, they are sperm (in males) or ova (in females).

In plants, male gametes are found in pollen grains and female gametes are found in ovules.

What are chromosomes and how many pairs do humans have?

Chromosomes are structures made of DNA found in the nucleus of nearly all cells. Humans have 23 pairs of chromosomes in each cell.

What is an allele?

An allele is a variation of a particular gene. Alleles can be dominant or recessive.

What does homozygous mean?

Homozygous means inheriting two identical copies of an allele, such as FF or ff.

What is the difference between a genotype and a phenotype?

A genotype is the combination of alleles that determine a characteristic, while a phenotype is the observable characteristics expressed by the alleles.

What is single gene inheritance?

Single gene inheritance occurs when a characteristic is controlled by a single gene, such as fur colour in dogs or red-green colour blindness in humans.
