I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
Because they are made to perform two different functions. Cells are part of tissues that are part of organs that perform a certain function. For example, your bone cells are made to make blood cells, so they wouldn’t be in your lungs as well.
Answer:
<h2>C.</h2>
Explanation:
This theory tells us that all cells come from existing cells, means all living cells come from the division of pre-existing cells. They do no come spontaneously from non- living matter as early believed. All pre-existing cells divide to form new cells by mitosis or meiosis. New cells never come from non-living matter suddenly, they only come from cell only.
