Terms The process that creates an egg or a sperm. Any cell with half of the original genetic material (Also referred to as a sex cell) Terms A version of a trait. Terms How many chromosomes do humans have? Produced by fertilization Terms The four nucleotide bases found in DNA. Terms If a skin cell has 50 chromosomes before dividing by meiosis into an egg/sperm – How many chromosomes does it have once it finishes cell division? If a skin cell has 50 chromosomes before dividing into 2 new cells – How many chromosomes does it have once it finishes cell division? Cell Division DNA is found in the _____. Occurs in the sex organs of an organism Cell Division A scientist removes a cell from an organism and observes it undergoing meiosis. At the end of meiosis, the scientist counts 7 chromosomes in each of the four cells that result. Based on this information, how many chromosomes would there be in a skin cell from the organism? Acquired or inherited? -- Hair dyed pink Occurs for the purpose of reproduction. Cell Division What is the probability of having a male child? Probability Based on the cross below – determine the probability of a yellow plant. Probability Based on the cross below – determine the probability of a heterozygous white rabbit. W = white w = brown Probability Based on the cross below – what is the probability that the offspring will express the recessive trait? Q Q q q Probability If a heterozygous fluffy tailed bunny is crossed with a heterozygous fluffy tailed bunny – what is the probability that a purebred fluffy tailed bunny will be produced? F = fluffy f = stubby tail Probability If a heterozygous brown haired father is crossed with a homozygous blond haired mother – what is the probability that a purebred blond offspring will be produced? B = brown b = blonde Probability Used to show relations between members of a family. Diagrams How are Mary and Peter related? Diagrams Who is Cheryl’s maternal grandmother? Diagrams How many paternal uncles does David have? Diagrams Do David and Mary have the same number of siblings? Diagrams Could Anne have inherited her brown hair from Dorothy? Diagrams Allele represented by a lowercase letter More Terms Change in the genetics of a species over time. More Terms An organisms genetic makeup. More Terms Example of an acquired trait. More Terms Each parent gives one allele to their offspring. More Terms Allele represented with a capital letter. Combining of two gametes in sexual reproduction. More Terms If you cross a male heterozygous for brown eyes with a female who is homozygous for brown eyes – What will the resulting phenotype ratio be? Criss Cross Cross of a purple people eater that is hybrid for horns with a purple people eater that does not have horns. Summarize the genotypes & phenotypes of the possible offspring. In purple people eaters, one-horn is dominant & no horns is recessive. Criss Cross If a solid colored cow gives birth to a spotted cow – what must both parents posses? Solid color in cows is dominant. Criss Cross A homozygous dominant brown mouse is crossed with a heterozygous brown mouse. Genotype Ratio: Phenotype Ratio: Criss Cross If two cats create offspring that are only heterozygous for long hair – what were the genotypes of both parents? Long hair in cats is dominant. Criss Cross In rabbits, grey hair is dominant to white hair. Also in rabbits, black eyes are dominant to red eyes. Which genotype describes a white haired, black eyed rabbit? a) Ggbb b) ggBB c) ggbb d) GgBb Criss Cross End Asexual reproduction is associated with which type of cell division. Cell Division The purpose of this cell division is to regenerate cells. Cell Division Creates a gamete. Cell Division
