Hello!
We all are very well familiar with Mendel's laws of inheritance. Just recalling Mendel's law of independent assortment that states, "alleles of different genes are inherited independently of one another".
Here we have two traits, and we want to know how the alleles of these traits will assort independently during the formation of gametes from two parents.
The two traits are:
- Flower color ( Can be purple or white)
- Seed shape (Can be round or wrinkled)
Here the alleles of the traits are represented by alphabets as:
- purple flowers: P
- white flowers: p
- round seeds: R
- wrinkled seeds: r
We have parent one as PpRr
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 1.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
We have parent two as PpRr :
The gamete formation of one trait (Pp) will be independent of the other trait (Rr) in Parent 2 as well.
- Gamete 1: PR
- Gamete 2: Pr
- Gamete 3: pR
- Gamete 4: pr
This shows that there is not restriction that the allele for wrinkled seed r will go with allele of white flower p because its recessive or allele of round seeds R will go with allele of purple flowers P because its dominant. There is no restriction when alleles are assorting into gametes and they can go randomly as per nature's choice with any one.
Hope it helps! :)

Answer:
A. The birth rate would likely increase.
Explanation:
if the quantity is analyzed in any time interval, the quantity at any given moment is the product of the previous quantity
Answer:
DNA never leaves the nucleus; RNA is in the nucleus and in the cytoplasm.
Explanation:
DNA and RNA differ from each other with respect to their structure, function, and location. DNA is always present in the nucleus and never leaves the nucleus.
DNA replication and transcription also occur in the nucleus to form DNA and RNA respectively.
On the other hand, RNA is present in both the nucleus and cytoplasm. The mRNA leaves the nucleus and enters the cytoplasm to serve as a template in protein synthesis. The rRNA and tRNA are also present in the cytoplasm.
This is necessary because if it ISN'T instinct then the young would die far more often.
