Ose Genetics

An individual who is heterozygous for two genes is represented:

• (A) AAbb

• (B) Aabb

• (C) AaBb

A geneticist crosses a plant with red flower to a plant with white flowers. The offspring included plants with red flower 1/4 pink flowers 1/2 and white flowers 1/4 which allele they are codominant.

• Nether they are codominant

• Red

• Neither they are incompletely dominant

A cross of white chick (WW) with black chick (BB) produces all special offspring WB This types of inheritance is known as:

• Codominance

• incomplete Dominance

• Dominant/recessive

when the genotype consist of a dominate and a recessive allele, the phenotypes will be like_ allele

• A. The Dominart

• B. The recessive

• Neither

which of the following would complete an example of incomplete dominance

• Brown and white coloring in guinea pig

• Red White Pink flower where the pigment is not produce equally

• None of above

Long radisher crossed with round radisher result in all oval radishers. this type of inheritance is:

• Co-Dominance

• Incomplete Dominance

• Complete Dominance

Normal human body cells contain how many chromosomes

• 46

• 44

• 23

• 69

which of following outcomes would you expect from the following: tall, round (TTRR) x short wrinkling (ttrr)

• All offspring would be short and wrinkled (ttrr)

• 9:3:3:1

• All offspring would be tall and round (TTRR or TtRr)
