Inherited traits are controlled by genes. Some genes have multiple forms called alleles. For example, Pod color in pea plants is controlled by a gene with 2 alleles. The allele for Green pea pods (G) is dominant to the allele for Yellow pea pods (g). List the 3 possible combinations of genotypes and their phenotypes for these alleles.

GG green, Gg green, and gg yellow.

Explanation:

GG is dominant, and Gg is dominant, but it has an indominant gene that doesnt show up, and gg is recessive. the yellow color will only show up in one of them, because the rest have the dominant trait of green coloring.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

hormones in blood stream

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
