Genotypes are made of 2 letters...
1) what do the letters represent?
2) where do they come from?
1) alleles
2) one allele is passed on from each parent

Why might asexual reproduction be inferior to sexual reproduction in an environment that changes frequently?
Asexual reproduction yields offspring with identical genes. The offspring wouldn't be able to adapt to survive unfavorable conditions.
300
How many offspring did F1 produce?
7
300
Provide the percentage probability of offspring that are homozygous dominant, homozygous recessive, and heterozygous.
50% probability of homozygous dominant offspring, 50% probability of heterozygous offspring

What pattern of inheritance do these cows show?
Codominance. The dominant alleles for reddish hair and white hair are both expressed in the phenotype.
300
What state is the largest by land area?
Alaska

A gardener uses a brush to collect pollen from one flower, then deposits the pollen from the swab on another flower. Is this sexual or asexual reproduction?
Sexual reproduction
400
How many carriers of sickle cell anemia are in F3?
4
400
If the probability of an offspring having blue skin is 75%, what are the genotypes of the parents?
Heterozygous (Bb)
400
A white and black dog produce a grey dog. What is this an example of?
Incomplete dominance

What is the largest ocean on Earth?
Pacific Ocean
500
How are genotype and phenotype related?
Phenotypes are how the genotypes for a trait manifest. Genotypes determine what version of the trait is observed. For example, a genetic monster with the genotype bb will exhibit the yellow phenotype for the skin color trait.

One head of garlic has 8 cloves. The head is taken apart and each clove is planted, resulting in 8 new garlic plants. Is this sexual or asexual reproduction?
Asexual reproduction

If individual W reproduced with a homozygous dominant individual, what possible genotypes could their offspring have?
SS or Ss
500
If F1 was 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive, what is the ratio of recessive to dominant phenotypes?
1:3 recessive phenotype to dominant phenotype
