<span>Mendel showed that the green-seed trait did not disappear but was only masked by breeding plants with only two alleles for the trait. After the cross of yellow seed, a small amount of offspring had green seeds. So, he concluded that the green-seed trait is masked by the dominant yellow-seed trait and that two alleles are necessary for green-seed trait to show up.</span>
Answer:
1. Circulatory System
2. Respiratory System
3. Endocrine System
4. Nervous System
5. Urinary/ Excretory System
Explanation:
1. Circulatory System- The heart pumps blood and blood vessels such as arteries and veins, transports the blood to every part of our body providing organs and muscles with nourishment.
2. Respiratory System- This system maintains our breathing. It supplies the body with oxygen for cellular respiration.
3. Endocrine System- The glands of the endocrine system secrete chemicals called hormones that regulate most of the processes in our bodies like growth, reproduction, metabolism, etc...
4. Nervous System- The entire nervous system controls all of the other systems of the body and it also transmits information to the brain, such as pain and external sensations.
5. Urinary/Excretory System- This system is responsible for eliminating waste products of metabolism and other materials from the body that are of no use.
Considering that the population of white flowers in which the frequency of red allele CR is p= 0.7, then the frequency of the white allele (CW) in the population will be p=0.3. This is because the population contains white allele and the red allele therefore the two should add up to 1. Allele is the alternative form of a gene that codes for a specific trait.
