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! :)
It would be the branch, wouldn't it?

Hello. This question is incomplete. The full question is:
Energy and matter cycle through a beach ecosystem on the Gulf of Mexico. Identify one kind of model you can use to show the path of energy and matter through this ecosystem. Describe one benefit of using that kind of model to show those processes.
Food web; shows energy available at each trophic level for the next group of organisms
Energy pyramid; show all pathways of energy flow in an ecosystem
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Answer:
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Explanation:
The food chain represents a linear sequence of energy transfer within an environment. This transfer is carried out with a sequence of living beings that serve as food for each other and this food that promotes the transfer of energy through a single path, allowing all levels of transmission to be observed, through primary, secondary and tertiary.
Answer:The Answer is A
Explanation:
Fungi are heterotrophs because they survive on other organisms.
