inheritance

Question 1

define genotype

Answer 1

genetic constitution of an organism (it describes all of the alleles that an organism has)

Question 2

define phenotype

Answer 2

observable or biochemical characteristics of an organism. Due to interaction between expression of genotype and environment

Question 3

define dominant

Answer 3

allele that is always expressed in the phenotype of an organism

Question 4

define recessive

Answer 4

allele is only present in phenotype when another identical allele is present

Question 5

define co dominant

Answer 5

alleles are both expressed in phenotype and neither is recessive

Question 6

define gene

Answer 6

specific sequence of bases on a chromosome that codes for one or more polypeptides

Question 7

define allele

Answer 7

different forms of a gene. most organisms carry 2 copies one from each parent. Represented by a letter

Question 8

define nucleotide

Answer 8

consists of an organic base, pentose sugar, phosphate. Basic units of DNA and RNA

Question 9

define locus

Answer 9

fixed position of a gene on a particular chromosome

Question 10

define homozygote

Answer 10

organism carries 2 copies of the same allele

Question 11

define heterozygote

Answer 11

organisms carries 2 different alleles

Question 12

define carrier

Answer 12

individual carrying an allele not expressed in the phenotype that could be passed on to offspring

Question 13

define multiple alleles

Answer 13

a gene that has 2 or more alleles
