In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is
Agata [3.3K]

Answer:

The question is incomplete, it lacks the main questions, those questions are:

a. What is the genotype for black chickens?

b. What is the genotype for white chickens?

c. What is the genotype for erminette chickens?

Explanation:

This question involves a gene coding for feather colour in some birds, in which the black allele (B) and white allele (W) is involved. According to the question, the gene coding for feather colour exhibits co-dominance i.e. both the black (B) and white (W) allele are expressed in a heterozygous state (BW) to form an erminette phenotype.

Hence, if the neither alleles is dominant or recessive over the other. The black phenotype will only be expressed when the genotype is BB.

The white phenotype will only be expressed when the genotype is WW

The combination of both alleles which results in the simultaneous expression of both in the erminette phenotype, will be BW genotype.

How does an organisms growth compared to the growth of an icicle
Travka [436]

Answer:

An icicle grows as water drips down the structure and freezes adding to its length and thickness. Organisms grow via the addition of new cells to the organs it contains. These organs grow from the inside out over the entire structure.

What is a difference between starch and glycogen?
deff fn [24]

The right answer is B.

Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.

Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.

Can someone write the first paragraph
Katena32 [7]

Hii!!

The purpose of mitosis is to create two new perfectly identical cells when either there is a need to replace old or damaged cells and to reproduce asexually by making new cells. Some organisms use mitosis to replace body parts. For example starfish replace lost arms by mitosis. Some organisms such as the hydra use mitosis to produce genetically identical offspring.

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin

● The order of the stages of mitosis can be remembered using the mnemonic PMAT.

Hope this helps!! if it has pls mark me as the brainliest Xd :D
