For a monohybrid cross for seed color (Y/y x Y/y), which gave a progeny ratio of what to what?
What is an example of a gamete?
What is the F1?
What is Mendel's second law?
For two heterozygous pairs, what is likely to happen in b, A/a and B/b?
What do we now know about the independent assortment law?
The ratio is 3 yellow:1 green
- F1 is the combination of the gametes.
- Mendel's second law is that different gene pairs on different chromosome pairs assort independently in gamete formation (meiosis).
b is just as likely to end up in a gamete with an a allele as with an A allele, and likewise for the B allele.
We now know that this law applies to genes on different chromosomes as genes on the same chromosome generally do not assort independently, because they are held together by the chromosome itself.
