12.1 The Work of Gregor Mendel
What plant did Mendel work with when studying genetics?
Pea Plant
what is an example of a phenotype?
Which parent gives you maternal inheretence
da mama
where are genes located?
on the chromosomes
What is a gene?
factors that are passed from one parental generation to the next.
what is an example of a genotype
Bb, BB, CC
what is an example of incomplete dominance?
pink flowers from red and white flower parents
Meiosis produces haploid cells, what does that mean?
Genetically unique, not the same.
What is a hybrid?
The offspring of crosses between parents with contrasting characteristics.
What is the difference between a phenotype and a genotype?
a genotype is is genetic makeup and a phenotype is a physical trait.
what is an example of codominance?
a spotted pig
what is one difference between meiosis and mitosis
answers may vary
- mitosis does not change the number of chromosomes of the original cell meiosis reduces the chromosomes number by 2
- mitosis produces diploid cells, meiosis makes haploid cells
- mitosis is in body cells, meiosis is in gametes
What are two types of gametes?
an egg and sperm
Why do we use a punnett square?
punnett squares use mathematical probability to help predict the genotype and phenotype combination in genetic processes.
give one example of the environment affecting your genes
sun, diet
What is Gene Linkage
Alleles of different genes tend to be inherited together from one generation to the next when those genes are located on the same chromosome.
What is segregation? (IN BIOLOGY)
separation of alleles when gametes are being made.
what is independent assortment
genes for different traits can segregate independently during the formation of genes.
Name all exceptions to Mendel's principles
Incomplete dominance,
Codominance,
Multiple alleles,
Polygenic traits
Name all the steps of meiosis (hint, don't forget cytokinesis)
PMAT I cytokinesis PMAT II cytokinesis
