Two mice breed. The male is heterozygous for the dominant traits of black fur and active behavior but is homozygous recessive fo
olya-2409 [2.1K]

Answer:

Four

Explanation:

Let the allele for black fur be B (the alternate will be b), the allele for active behavior be A (the alternate will be a), and the allele for light eyes be L (the alternate will be l).

<em>Heterozygous dominant for black fur = Bb</em>

<em>Heterozygous dominant for active behavior = Aa</em>

<em>Homozygous recessive for light eyes = ll</em>

Hence, the genotype for a male that is heterozygous for the dominant traits of black fur and active behavior but is homozygous recessive for light eyes will be BbAall.

Bb   Aa   ll

Possible Gametes

<em>BAl, Bal, bAl, and bal</em>

Therefore, the number of different types of gametes produced by the male mouse is four.

marta [7]

The addition of dynactin caused dynein to travel farther along the micro tubule.

<u>Explanation:</u>

Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.

Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
