A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in the F1 generation had black coa

ts. When these mice were crossed, they yielded 961 black coated mice and 317 brown coated mice. How could you account for the ratio of black coated to brown coated mice in the F2 generation? Select all that apply. A. The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color. B. The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color. C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele. D. The brown allele is not independent from the black allele and disappears in the F1 generation.

Answer:

C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Explanation:

Assuming the black genotype is BB and the brown genotype is bb.

At F1:

                 BB   x   bb = All Bb (black)

At F2:

                  Bb   x   Bb = BB (black), 2Bb (Black), bb (brown)

Th ratio of black to brown is 3:1

961 black : 317 brown is approximately 3:1.

Hence, the correct option is C.

<em>An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele</em>

What are the phases of a stem cell? List them in order.
jek_recluse [69]

There are three phases of stem cells mitosis, gene expression, and differentiation.

<h3 /><h3>What are stem cells?</h3>

Stem cells that are totipotent or omnipotent. programmable stem cells. Multiple-potency stem cells, stem cells with oligopotency, the body's building blocks are stem cells, which are cells that give rise to all other cells with specific roles.

Daughter cells are created when stem cells divide properly in the body or a lab to create additional cells. Most stem cells are found in the bone marrow.

They divide at this stage to produce new blood cells, Once fully developed, blood cells leave the bone marrow and travel into circulation.

Therefore stem cells develop into different cells through differentiation.

Which is true of genes? Question 4 options: They are proteins that produce sections of DNA which control the cell's activities.
OleMash [197]

The fundamental and functioning unit of genetics is called genes. They are units of DNA that produce proteins that control the characteristics of organisms.

<h3>What is the role of genes?</h3>

Genes are the basic and fundamental of inheritance and are made up of deoxyribonucleic acid. The variation of the gene of the same trait forms the alleles.

They code for the proteins that produce protein or RNA structures. Genes are located on the chromosome structure and code for proteins that play an important function and role in cell activity.

Therefore, option D. genes are a section of DNA that codes for proteins is correct.
