More about Traits
The meaning of homozygous dominant
What is a genotype that has 2 dominant alleles
The effect of mitosis in the human body
What is growth?
The genetic makeup of an organism's trait, shown with two letters representing two different alleles
What is genotype?
The number of chromosomes in a human cell (not a gamete)
What is 23 pairs or 46?
The four bases that link the phosphate backbones together and the pairs they appear in.
What is adenine and thymine, and cytosine and guanine.
The meaning of homozygous recessive
What is a genotype that has two recessive alleles?
The main point of meiosis
What is to divide the chromosomes and end up with gametes that only have 23 chromosomes
The observable traits of an organism
What is phenotype?
The number of chromosomes in a gamete
What is 23?
The shape of a DNA strand
What is a double helix?
The meaning of heterozygous
What is a genotype that has two different alleles?
The effect of "crossing over" during meiosis
What is that the genes "mix up" and the resulting gamete is genetically varied from the original cell?
Three examples of phenotypes
What are ____________, ____________, and ________?
The two different types of gametes
What is a sperm and egg?
The "A" in DNA stands for this word.
What is acid?
The point of doing a Punnett square
What is to figure out the probability of having a certain genotype and phenotype?
An example of when or where mitosis happens
What is ______________________ ?
The effect of the "dominant" trait
What is that the "dominant" trait always wins or dominates a recessive trait, so it will always show up as the phenotype.
The most important difference between sexual reproduction and asexual reproduction
What is that sexual reproduction produces genetically varied offspring while asexual reproduction produces genetically identical offspring?
The function of the phosphate backbone
What is to give shape and structure to the DNA?
The effects of gene mutation - positive, negative, or neutral
What is all three - positive, negative, or neutral?
(Not a mitosis question) The process of determining probability of a genotype and phenotype from a Punnett Square - task on the board.
What is __________?
When one gene substitutes, inserts, deletes, or shifts
What is mutation?
The reason the number of chromosomes in a gamete (23) is important
What is that there can only be 23 chromosomes because the gamete will combine with another gamete and create a cell that has 23 pairs (or 46) of chromosomes, the correct number for life to flourish
