1
Q
Gamete
A
Sperm or egg; a single set of genetic instructions; a haploid cell
2
Q
Zygote
A
The fertilised egg and all body cells; a double set of genetic instructions in a diploid cell
3
Q
Locus
A
The chromosomal location of a genetic instruction; e.g. the locus for the ABO blood group
4
Q
Allele
A
Alternative forms at a particular locus – the allele for A, B, or O blood group
5
Q
Dominant inheritance
A
Every affected parent will (probably) be A/a and every unaffected child will be a/a
6
Q
Recessive inheritance
A
An affected child must be homozygous recessive (a/a) and its parents must be heterozygotes (A/a)
7
Q
Law of Independent Assortment
A
During the formation of gametes, the segregation of alleles at one locus is independent of that of the segregation of alleles at any other.
