Question | Answer |
a organism where the 2 alleles factors are different (Rr) | hybrid |
what type of plants did Mendel use | Pea Plants |
f2 stands for ------------ etc. | second generation |
study of inheritance | genetics |
the from parent to offspring | inheritance |
a section of chromosomes that specifics a trait or protein | genes |
the 2 genes that carry information for the same traits are called | alleles |
an organism where both alleles are the same (AA or aa) | purebred |
according to Mendel how many factors are there for a trait | at least 2 |
uniting of a reproductive | fertilization |
the mating of an organism to see how the offspring inherits | cross (x) |
what is expressed if present? | dominant allele |
difference between recessive and dominant | if a dominant allele is present it will always be expressed and the recessive will be hidden |
not expressed if a dominant allele is present | recessive allele |
dominant allele is always represented by | a upper case letter |
the physical appearance is | phenotype |
genes of genetics of a person | genotype |
the 1st cell after the union of the reproductive cells | zygote |
a recessive allele is represented by a | lower case letter |
all of Mendel's f1 generation appeared ? | tall |
f1 stands for | first generation |
father of modern day genetics | Gregor Mendel |
the 4 steps in mendel's experiment | 1. made sure he had purebred parents 2. crossed parent with opposite traits 3. observed f1 and recorded results 4. continued this by crossing f1, f2, f3, etc generations & looking at the results |
2 things mendel discovered | 1. each trait had 2 factors one from each plant 2. the traits could be represented by a dominant allele or recessive allele |
2 examples of dominant traits in humans | brown eyes are dominant tongue rolling is dominant |
2 examples of recessive traits in humans | attached earlobes is recessive left handed is recessive |
what are the two types of alleles | dominant, and recessive |
