) When predicting the phenotype of the offspring from a dihybrid cross, why is it so important that each gene is located in a di
Bond [772]

Answer:

a) The genes present on separate chromosomes exhibit indepedent assortment.

b) The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

Explanation:

a) In a dihybrid cross, if the genes are present on the same chromosome, they will not exhibit independent assortment. The genes present on the same chromosome are called linked genes. Linked genes are inherited together. The absence of independent assortment of a linked gene gives more of parental types in F2 progeny. Therefore, if genes are not present on a separate chromosome, Mendel’s ratios deviate.

b) Alleles for tallness and purple flower are dominant. In the progeny, all the plants are tall. This means that the dominant tall plant is homozygous. With respect to flower color, the trait exhibits segregation of dominant and recessive alleles and both purple and white flower progeny are obtained. This makes both the plants heterozygous for the flower color gene.  

The genotype of tall and purple flower parent= TTPp

The genotype of short and purple flower parent: ttPp

How do Euglena and sperm cells use flagella?
loris [4]

Answer:

All euglena have chloroplasts and can make their own food by photosynthesis. ... Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.

Explanation:

In general, flagellum is a long whip like organ which protrudes to the exterior from the cell body and permits mechanical work without any marked change in the form of the effector cell. In Euglena, there are two flagella. One of them is equal in length to body while other is short.
