Unit 7 Vocabulary Assignment
Wow! Look at Those!
Gene
-functional unit that controls inherited trait possession that is passed on from one generation to another.
Homologous Chromosome
-one of the two paired chromosomes, one from each parent, that carries genes for a specific trait at the same location.
Hold Your Horses!
Gamete
-a haploid sex cell, formed during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg.
Law of Segregation
-Mendelian law stating that two alleles for each trait separate during meiosis.
Phenotype
-observable characteristic that is expressed as a result of an allele pair.
Hybrid
-organism heterozygous for a specific trait.
Genetic Recombination
-new combination of genes produced by crossing over and independent assortment.
Law of Independent Assortment
-Mendelian law stating that a random distribution of alleles occurs during the formation of gametes.
Tell Me More!!
Recessive
-Mendel's name for a specific trait hidden or masked in the F1 generation.
Dominant
-Mendel's name for a specific trait that appeared in the F1 generation.
Homozygous
-organism with two of the same alleles for a specific trait.
Well Hello There!
Allele
Genetics
-alternative form that a single gene may have for a particular trait.
-science of heredity.
Genotype
Heterozygous
-an organism's allele pairs.
Meiosis
-organism with two different alleles for a specific trait.
-reduction division process, occurring only in reproductive cells, in which one diploid (2n) cell produces four haploid (n) cells that are not genetically identical.
Diploid
-having two copies of each chromosome (2n).
Crossing Over
-exchange of chromosomal segments between a pair of homologous chromosomes during prophase 1 of meiosis.
Whats This Here?
Zygote
-fertilized egg formed when a sperm cell penetrates an egg cell.
Fertilization
-process by which haploid gametes combine, forming a diploid cell with 2n chromosomes, with n chromosomes from the female parents and n chromosomes from the male parent.
Haploid
-cell with half the number of chromosomes (n) as a diploid (2n) cell.
the male and female gametes are haploid
