7 genotypes and phenotypes

Question 1

define genotype

Answer 1

both the double set of genetic instructions present in a diploid organism and the genetic makeup of an organism at one particular gene locus

Question 2

explain the difference between homozygous, heterozygous and hemizygous genotypes

Question 3

write genotypes for genes with two alleles

Question 4

write genotypes for genes with multiple alleles

Answer 4

I^A i (AO)

Question 5

write genotypes for sex-linked genes

Question 6

define phenotype

Answer 6

an observable or measurable characteristic of an organism that is the product of genetic and environmental factors
