Bio meiosis and genetics Flashcards
Why is Meiosis important for genetic diversity
It shuffles genes to make sure offspring are different
How’s crossing over important for genetic diversity
It creates genetic variation
When does crossing over occur?
In prophase
What is the difference between haploid and diploid cells
Haploid contains one set of chromosomes, and diploid has two.
How are gamete cells and somatic cells similar? How are they different?
Somatic and gamete cells are similiar because they both go through PMAT, but are different because somatic is a body cell, and gamete is a sex cell.
What roles do meiosis and mitosis serve in an organism? How are they alike? How are they different?
Meiosis and mitosis is the duplication of cells. They are alike because they both do the same cycle. The difference is meiosis goes through PMAT 2 times while mitosis goes through once.
how crossing over and independent assortment help provide genetic
variability
Because the crossing over makes the chromosomes all unique from each other.
What incomplete dominance? Give an example
Incomplete dominance is when two different traits are paired together and blended. An example is a red flower and a white flower make pink.
What is codominance
Codominance is when two different traits are mixed together and have spots/stripes. An example is a red flower and a white flower paired together. Some of the petals will be red and some will be white
What is the difference between diploid and haploid cells?
Haploid cells have one of each chromosome, while diploid has homologous pairs
