Genetics Review

The different forms of a gene are called

• traits
• pollinators
• alleles
• hybrids

This type of inheritance pattern is a MIXTURE of both traits.

• incomplete dominance
• co-dominance
• complete dominance
• recessive pattern

What genotype is missing from this Punnett Square?

• RrYy
• RRYY
• rryy
• RrYY

inheritance pattern in which a heterozygote expresses the distinct traits of both alleles

• codominance
• intermediate inheritance
• genetic locus
• sex linked gene

When an area of a chromatid is exchanged with the matching area on a chromatid of its homologous chromosome, _________________ occurs

• crossing over
• mutagenesis
• hybridization
• fertilization

What kind of cells are made in MEIOSIS?

• Haploid Gametes
• Diploid Somatic Cells
• Skin Cells
• Liver Cells

The physical appearance of the allele combination the offspring receives

• genotype
• homozygous
• phenotype
• dominant

Phenotypes which result as a combination of MANY genes, such as skin color and eye color, are known as ______________ traits.

• Monogenic
• Dihybrid
• Multiple Allele
• Polygenic

Freckles (F) are dominant over nonfreckles.   What is the phenotype of individual #3

• Ff
• ff
• freckles 
• nonfreckles 

If red flowers (R) are dominant over white, what is the probability that the offspring will be red? 

• 1 out of 4
• 2 out of 4
• 3 out of 4
• 4 out of 4
