The F1 progeny will all have the genotype Zz and will all have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)
In chickens, congenital baldness is due to a z-linked recessive gene. T
his means that the gene for baldness is located on the Z chromosome and an individual must have two copies of the recessive allele to exhibit the bald phenotype.
The bald rooster has the genotype ZZ, meaning he has two copies of the recessive allele. The normal hen has the genotype Zz, meaning she has one copy of the recessive allele and one copy of the dominant allele.
When these two individuals are mated, all of the F1 progeny will have the genotype Zz and will have normal feathers. When the F1 progeny are interbred, the F2 progeny will have the following genotypes and phenotypes:25% ZZ (bald)25% Zz (normal)50% zz (normal)
The expected proportions for the F1 and F2 progeny are as follows:F1: 100% Zz (normal)F2: 25% ZZ (bald), 25% Zz (normal), 50% zz (normal)
To know more about genotypes and phenotypes here:
true or false
Answer: True
Explanation:
The chlorophyll of all the green organisms lies in the chloroplast. It is a green colored pigment which helps in trapping the sunlight from the sun.
The trapped sunlight is used as a source of energy in order to convert this energy into chemical energy.
Carbon dioxide and water is added for the formation of carbohydrates in the plants.
Answer: The correct answer for the blank is-

Proteins and complex carbohydrates are part of the four major macromolecular groups and play crucial roles in our body functions and energy provision. They are essential in our diet, assisting in maintaining connective tissue, aiding blood clotting, and providing energy for our bodies.
Proteins and complex carbohydrates are both part of the four major macromolecular groups, which also involve lipids and nucleic acids. These macromolecules are vital to the human diet, providing fuel for the body, and undergo digestion and energy production processes. Carbohydrates can be both complex, like starch and glycogen or simple sugars like glucose and fructose. These sugars are key contributions to ATP production in cells, and glucose specifically, is controlled by a variety of endocrine mechanisms to regulate its presence in the bloodstream. The excess glucose is stored as glycogen in the liver and skeletal muscles, or instead transformed into fat in adipocytes.
Proteins along with carbohydrates are also essential in the maintenance of connective tissue and assisting in blood clotting. This prominence of these macromolecules in the diet is why athletes often 'carb-load' before engaging in major competitions, allowing their bodies to possess enough energy to compete at such high levels. Foods like grains, fruits, and vegetables are all natural carbohydrate sources, providing us with the glucose our bodies require. Therefore, proteins and complex carbohydrates showcase inherent essentiality within the human diet, playing significant roles in body function and providing necessary energy for activities.
