Allele -ANSWER✅✅✅A particular version of a gene.
Same locus on same chromosome type.
Same length, same switches, same activators.
Similar nucleotide sequence but NOT identical.
Crossing Over -ANSWER✅✅✅The exchange of segments of non sister chromatids
between a pair of homologous chromosomes that occurs during meiosis 1.
Cytokinesis -ANSWER✅✅✅Division of the cytoplasm to form two daughter cells.
Typically occurs immediately after division of the nucleus by mitosis or meiosis.
Dihybrid Cross -ANSWER✅✅✅A mating between two parents that are heterozygous
for both of the two genes being studied.
Dominant -ANSWER✅✅✅Referring to an allele that determines the phenotype of a
heterozygous individual.
Fertilization -ANSWER✅✅✅The fusion of an egg and a sperm to form a diploid zygote.
DNA molecules NOT fuse during fertilization.
Gamete -ANSWER✅✅✅A haploid reproductive cell that can fuse with another haploid
cell to form a zygote. Most
multicellular eukaryotes have two distinct forms of gametes: egg cells (ova) and sperm
cells.
, Gene -ANSWER✅✅✅A section of DNA that encodes a protein (or a functional RNA)
and its associated regulatory sequences.
Genotype -ANSWER✅✅✅All of the alleles of every gene present in a given individual.
May refer specifically to the alleles of a particular set of genes under study.
Haploid number -ANSWER✅✅✅The number of distinct chromosome sets in a cell.
Symbolized as n.
Heterozygous -ANSWER✅✅✅Having two different alleles of a certain gene.
Homologous Chromosomes -ANSWER✅✅✅In a diploid organism, chromosomes that
are similar in size, shape, and gene content. Homologs carry the same genes in the
same location, but may carry different versions (alleles) of those genes.
Homozygous -ANSWER✅✅✅Having two identical alleles of a certain gene.
Independent Assortment -ANSWER✅✅✅The concept that each pair of hereditary
elements (alleles of the same gene) behaves independently of other genes during
meiosis.
Law of Segregation -ANSWER✅✅✅The concept that each pair of hereditary elements
(alleles of the same gene) separate from each other during the formation of offspring
(i.e., during meiosis).
Locus -ANSWER✅✅✅A gene's physical location on a chromosome.
Meiosis 1 -ANSWER✅✅✅The first cell division of meiosis, in which synapsis and
crossing over occur, and homologous chromosomes are separated from each other,
producing daughter cells with half as many chromosomes (each composed of two sister
chromatids) as the parent cell.
Meiosis 2 -ANSWER✅✅✅The second cell division of meiosis, in which sister
chromatids are separated from each other. Meiosis 2 does not reduce chromosome
number.
Meiosis -ANSWER✅✅✅In sexually reproducing organisms, a special two-stage type of
cell division in which one diploid (2n) parent cell produces 4 haploid (n) reproductive
cells (gametes); results in halving of the chromosome number.
Model Organism -ANSWER✅✅✅An organism selected for intensive scientific study
based on features that make it easy to work with (e.g., body size, life span), in the hope
that findings will apply to other species.
