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! :)

Complete question:
Which survivorship curve best describes most marine organisms (few adults produce a large number of eggs and larvae).
- Type I
- Type II
- Type III
- None of the above
Answer:
<em>Type III </em>
Explanation:
There are three survivorship curves, each of them corresponding to different species according to their reproductive strategies.
- <u>Type I</u><u>.</u> Organisms do not tend to die when they are young or middle-aged, but they do when they are old. These species, in general, have a few descendants and parents provide much parental care to ensure their progeny to survival.
- <u>Type II.</u> Organisms that have more or less the same probabilities of dying in each age interval. These organisms can also have a few descendants and they can provide significant parental care.
- <u>Type III</u>. Only a few individuals survive their first period of life or their firsts years. However, the lucky ones to reach a certain age generally have a long life. These organisms have a lot of descendants at the same time, but they do not provide much parental care. This is the case of most marine organisms that produce a large number of eggs and larvae when they are adults, but they do not provide parental care.
