genetics terminology

Question 1

alternative form of gene

Answer 1

allele

Question 2

mating between 2 individuals (involving the formation of gametes and their subsequent fusion, to give rise to offspring)

Answer 2

cross

Question 3

law of segregation ?

Answer 3

-during gamete formation
= alleles separate
= each haploid games carries only one allele for a characteristic

Question 4

fertilisation restores diplod condition durin ?

Answer 4

sexual reproduction

Question 5

both alleles are the same

Answer 5

homozyguous

Question 6

alleles for a particular trait are different

Answer 6

heterozyguous

Question 7

law of dominance =

Answer 7

dominant allele = expressed, recessive = masked

Question 8

specifies actual alleles present for a particular characteristic

Answer 8

genotype

Question 9

trait for a characteristic that is expressed or displayed on individual

Answer 9

phenotype

Question 10

two individuals which are heterozygous for a single characteristic are cross bred

Answer 10

monohybrid cross

Question 11

each allele is an independent unit that is inherited on its own

Answer 11

law of independent assortment

Question 12

specific place on chromosome where a gene is found

Answer 12

locus

Question 13

a cell with only one copy of each gene

Answer 13

haploid

Question 14

used to calculate the probability of chance of the expression of a particular trait
