When Mendel crossed two hybrid plants for stem height (Tt), what results did he always get?

When you cross two hybrids, the results always come in a 3:1 ratio as follows:

3 is the inheritance of at least 1 dominant allele
1 is the inheritance of two recessive alleles

Punnet Squares are very useful!
     <u>T     t  </u>
T | TT | Tt |
t  |<u> Tt | tt  </u>|

Three out of 4 boxes have offspring that express the dominant trait (tall plants) and 1 out of 4 boxes expresses only the recessive trait (short plants).

Hope this helps! :)

Can you define and identify the significance of Okazaki fragments, DNA ligase, and primer RNA during DNA replication?a. Okazaki
Neko [114]

Answer:

a. discontinuous

b. lagging

c. phosphodiester bonds

d. DNA polymerase I

e. RNA primase

Explanation:

Okazaki fragments are so called because these are synthesized in a discontinuous unlike in the leading strand where the new DNA strand is synthesized continuously. This is due to the fact that the lagging strands runs in the 5' to 3' direction, thus, a means has to be devised such that new DNA can be synthesized in the 5' to 3' direction. DNA ligase aids in ligating these fragments together. DNA polymerase can not begin the synthesis of the new DNA strand thus, the RNA primers helps to perform this function.
