monohybrid cross and dihybrid codominance

Question 1

What is monohybrid?

Answer 1

= single leter
= capital or lower case

Question 2

What are the gametes?

Answer 2

= there should be 4 gametes
= each allele should be in a gamete

Question 3

What is dihybrid?

Answer 3

= when there are 2 characteristics these are each encoded by 2 alleles of a gene
= So like tall plants nd shoer plants, T for tall and t for short
and then red or yellow
R for red
r for yellow

Question 4

How do we do these dihybrid crosses?

Answer 4

= You would find the combination between the pairs of alleles for each parent so if it is:
TTrr it can mix to be Tr and thats the only comnination
If there is:
ttRR the combination is TR
so these are the only 2 gametes but there cold be more
* MIX BETWEEN THE TWO CHARACTERISTICS

Question 5

What is co-domimance?

Answer 5

= both alleles of a gene, are equal domiance , so there may be 3 possible phenotypes

=

Question 6

What do the gametes contain?

Answer 6

= only one copy of each letter
