multi trait inheritance (genetics)

Question 1

Monohybrid meaning

Answer 1

based on 1 characteristic (i.e., plant height)
controlled by 1 gene

Question 2

Dihybrid Cross

Answer 2

based on 2 characteristics
controlled by 2 genes
consists of heterozygous alleles

Question 3

what is a dihybrid cross used for?

Answer 3

based on 2 characterisitcs
controlled by 2 genes
(these genes can be continous or discontinious)

Question 4

what are mendels laws?

Answer 4

-> each pair of alleles segrgate independently during gamate formation (have their own section to cross)
-> heterozygous parents with 2 traits will produce 4 possible gamates (combinations of alleles)

Question 5

what is the product law?

Answer 5

The probability of 2 independent random events both occurring, is the product of the individual probabilities of the events

->how likely is something foing to happen, add the probabilities together as more events pair together

Question 6

discontinious variation

Answer 6

when the expression of the products of one gene has no effect on the expression of the products of a second gene

Question 7

continious variation

Answer 7

when the product of one gene is affected by the product of another gene
the gene products may be additive or one product may negate the other product
