Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.

What are proteins for collagen?
In-s [12.5K]

Answer:

Collagen is a protein made up of amino acids glycine, proline, hydroxyproline and arginine — all of which help our body's connective tissue, skin, hair and nails stay as healthy as possible.** As we age, and the more stress we put on our body, the greater the impact on collagen production.

A woman with color-normal vision, but whose father was color blind, marries a man with normal vision. They are expecting a child
kotegsom [21]

To know what happens here, you need to analyze the alleles.

If the father is color blind and the daughter is not, you can suppose that is a recessive allele.

You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).

When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.

So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.

Define and distinguish between a hypothesis and a scientific theory
Annette [7]

A hypothesis is an idea or explanation that you then test through study and experimentation. A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. . Most hypotheses can be supported or refuted by experimentation or continued observation. Theory: A theory is more like a scientific law than a hypothesis. I hope this helps! Please give me stars to tell me how well I'm doing.
