Is anybody out there???? (I feel like I'm talking to myself).

Does probability tell what will happen or what is likely to happen?
What is probability describes how likely it is that an event will occur.

A characteristic, such as seed color in peas or hair color in humans is known as a ...
What is a trait?

Look at the chromosome pair on page 96. Which genes are homozygous? (Keep the page open for the next question).
What is cc, ee, FF, GG, II

List possible percentages when completing Punnett squares.
What is 0%, 25%, 50%, 75%, and 100%.

What should you always do to a lowercase letter?
What is underline it. (I can't in this program or this whole sentence would have been underlined)!

If I flip a coin ten times and the first five times I get a heads, what is the likelihood that the next flip will be tails?
Why?
What is still 50% because one coin toss does not affect the results of the next coin toss.

The passing of traits from parents to offspring is called heredity. The study of heredity is called...
What is genetics?

Look at the chromosome pair on page 96. Which genes are heterozygous?
What is Aa, Bb, Dd, Hh
200
Cross two heterozygous parents. Determine the percentage of offspring that would carry the recessive trait.
What is 25%. You would have BB, Bb, Bb, and bb. 1/4.

What are some GREAT letters to use when doing a Punnett square?
What is Aa, Bb, Dd, Ee, Ff, Gg, Hh, Nn, Rr

What is the chance of a couple having a boy? Show the Punnett square with the correct genotypes.
What is 50%. You should have a Punnett Square crossing XX and XY. Remember: BoY-the Y in boy reminds you that XY is the male. :)

What two terms can be used to describe the genotype:
bb
What is homozygous recessive or purebred recessive. Homozygous and purebred because the alleles are the same and recessive because they are both lowercase letters.
300
What is bigger: a gene or chromosome?
What is chromosomes. Genes are located on chromosomes so the chromosome has to be bigger.

Cross a homozygous dominant pea that is round with a heterozygous pea plant. What are the chances the offspring will be round?
What is 100%. You should have two RR and two Rr.

What are the WORST letters to use when doing a Punnett square?
What is Cc, Ii, Jj, Kk, Ll, Mm, Oo, Pp, Qq, Ss, Uu, Vv, Ww, Xx, Yy, Zz
On the quiz, the book actually uses the letter Ww. :( Why?

What is the chance of drawing a 7 of hearts from a deck of cards?
What is one in 52.
400
What two terms can be used to describe the genotype:
Bb
What is heterozygous or hybrid. (Notice that you do not put dominant or recessive after these terms because they are different).
400
Could the genotypes BB, Bb, and bb all have the same phenotype? Why/Why not?
What is no, the genotypes BB, Bb, and bb cannot have the same phenotype. bb would have the recessive trait because there is no capital letter present.

In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). In a cross between a heterozygous black guinea pig and a homozygous white guinea pig, what is the probability that an offspring will have white fur? Use a Punnett square. :)
What is You should have crossed Bb and bb so there would be a 50% chance that an offspring will have a white coat (bb).
400
A great strategy when setting up a Punnett Square is to ...
What is use two different colored highlighters!!! Can we do that on the quiz???
YES!!!!!!!!!!!!!

What are the chances of being born on a leap day (February 29th)?
What is The chance of being born on a leap day is often said to be one in 1,461. Four years is 1,460 (365 x 4) days and adding one for the leap year you have 1,461. So, odds are 1/1,461.

What two terms can be used to describe the genotype:
BB
What is homozygous dominant or purebred dominant-
Homozygous or purebred because the alleles are the same and dominant because they are both capital letters.

Draw a picture/sketch and label the following:
cell, nucleus, chromosomes, DNA, gene
What is look on page 98. :)

In rabbits, the allele for a sotted coat is dominant over the allele for a solid-colored coat. A spotted rabbit was crossed with a solid-colored rabbit. The offspring all had spotted coats. what are the probable genotypes of the parents? Explain.
What is The solid colored parent must be homozygous recessive and the spotted parent is probably homozygous dominant. If the spotted parent were heterozygous, then there would have been solid colored offspring (about 50%).

How many cups of coffee do I average a day?
What is zero. I have never had a cup of coffee in my life. I once had a sip in college but I hated it. I drink about 5-7 cups of tea a day. Notice my new tea holder??? Thank you, Mr. Achin!
