Question | Answer |
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 |
