In flowers, red (R) is dominant over yellow (r) . What would be the potential phenotypes of potential offspring if parent 1’s genotype is RR and parent 2’s is rr?
100% red
_____ plants are a good choice to use by Mendel because they are fast growing and easy to raise.
Pea
Explain the Law of Dominance.
the dominant allele is expressed over the recessive allele
_________ is the physical appearance of a trait
Phenotype
A __________ allele will always express itself regardless of what other allele it is paired with
Dominant
This law states that the two alleles for each trait separate during meiosis so each gamete carries only one allele for each trait.
Law of Segregation
Is Rr homozygous or heterozygous?
Heterozygous
The plant is tall. Is this a phenotype or genotype?
Phenotype
What are the different forms of a gene called?
alleles
Explain Mendel's law of independent assortment.
Each pair of alleles segregates independently of each other pair of alleles during gamete formation. Only applies to genes located on different chromosomes
What are the chances of a woman with Type AB and a man with Type A having a child with Type O?
0%
How many alleles for a trait will you pass on to your child?
1
If black fur is dominant and white fur is recessive, what color fur will a cat with the genotype ff have?
White
True or False: A dominant trait is only shown if there are two dominant letters present.
False
Who is the father of modern genetics?
Gregor Mendel
True or False: In his genetics experiments with pea plants, Gregor Mendel determined traits were passed down in a random pattern.
False: It is in a predictable pattern
________ is a diagram that is used to predict the genotypes of a particular cross or breeding experiment
Punnett square
A _________ allele is masked when a dominant allele is present
recessive
If brown eyes are dominant and blue eyes are recessive, what color eyes will someone with the genotype Bb have?
Brown eyes
