5 Written Questions

1. the transfer of pollen from male reproductive structures (anther) to female reproductive structures (stigma) in plants
2. a condition in which a trait in an individual is intermediate between the phenotype of the individual's two parents because the dominant allele is unable to express itself fully; example: pink flowers are the offspring from red and white flowers
3. a haploid reproductive cell that unites with another haploid reproductive cell to form a zygote
4. an organism's genetic makeup, or allele combinations
5. pattern where phenotypes of both homozygote parents are produced in heterozygous offspring so that both alleles are equally expressed; example: black checkered chicken

5 Matching Questions

1. law of independent assortment
2. hybrid
3. sex chromosome
4. multiple alleles
5. allele

1. a one of two alternate forms of a gene that can have the same locus on homologous chromosomes and are responsible for alternative traits
2. b three or more forms of a gene that code for a single trait; example: blood types: A, B, and O
3. c a chromosome that determines the sex of an individual; X or Y. Females are XX and males are XY
4. d an organism that is the offspring of genetically dissimilar parents or stock; usually the genotype is heterozygous and the phenotype is dominant
5. e each member of a pair of homologous chromosomes separates independently of the members of other pairs so the results are random

   True        False

4. phenotype → what an organism looks like as a consequence of its genotype

   True        False

5. sex-linked trait → a trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome or the Y chromosome in humans

   True        False
