two different alleles

Answer 10

heterozygous

what are the synonyms for heterozygous

Answer 11

hybrid/a carrier

Question 12

The breeding of a known and an unknown to determine the unknowns genotype and phenotype

Answer 12

testcross

Question 13

The ______ States each pair of alleles segregates into gametes independently

Answer 13

law of independent assortment

Question 14

The _____ States that the probability of a compound event is equal to the product of separate probabilities of independent single events
