|---|---|---|---|---|---|
| What is variation? | Differences between members of the same species.
🗑
|
||||
| Blue monsters were crossed with yellow, all the offspring are blue. Which characteristic is recessive? | Yellow
🗑
|
||||
| Blue fur is a dominant characteristic (allele B). What could the genotype of blue bat be? | BB or Bb
🗑
|
||||
| What are the different variants of the same gene called? | Alleles
🗑
|
||||
| If two heterozygous yellow Tombliboos are crossed, what proportion of the litter will be of the recessive green colour? | one quarter
🗑
|
||||
| What is polygenic inheritance? | Inheritance of characteristics conterolled by more than one gene.
🗑
|
||||
| What is the phenotype ratio resulting from a cross of two heterozygous individuals? | 3:1 (3 x dominant : 1 x recessive)
🗑
|
||||
| What is the genotype ratio resulting from a cross of two heterozygous individuals? | 1:2:1 (BB:2xBb:bb)
🗑
|
||||
| What is a phenotype? | How individual looks as a result of their genes.
🗑
|
||||
| What does genotype tells us? | Which alleles the individual carries. BB or Bb or bb etc.
🗑
|
||||
| Why is the expected ratio not always seen in nature? | each fertilization is an idependent event so smaller the sample size greater the chance of difference from the expected ratio, also different alleles survive better.
🗑
|
||||
| Male gametes in humans are produced in | Testes
🗑
|
||||
| Human male gametes are called | Sperm cells
🗑
|
||||
| Why are the human egg cell the biggest cells in the female body? | Egg cells contain the food store for the developing baby
🗑
|
||||
| Female gametes in plants are called | Ovules
🗑
|
||||
| Female gametes in plants are contained in | Ovaries
🗑
|
||||
| Male gametes in plants are contained in | Anthers
🗑
|
||||
| Male gametes in plants are called | Pollen
🗑
|
||||
| Female gametes in humans are contained in | Ovaries
🗑
|
||||
| Genetic information is stored in an organelle called a | Nucleus
🗑
|
||||
| Molecule that stores genetic information is | DNA
🗑
|
||||
| DNA in a nucleus is organized into | Chromosomes
🗑
|
||||
| Full set of chromosomes is called a | Chromosome complement
🗑
|
||||
| A full human chromosome complement consists of | 46 chromosomes
🗑
|
||||
| Cells with full chromosome complement are called | Diploid
🗑
|
||||
| Cells with half of chromosome complement are called | Haploid
🗑
|
||||
| Human haploid chromosome complement consists of | 23 chromosomes
🗑
|
||||
| Egg cell and sperm cell are called | Gametes
🗑
|
||||
| In fertilization gametes combine to form a | Zygote
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
