Assume that the genes for tan body and bare wings are 15 map units apart on chromosome II in Drosophila. If a tan-bodied, bare-w

inged female was mated to a wild type male and the resulting F1 phenotypically wild type females were mated to tan-bodied, bare- winged males. Of 1000 offspring, what would be the expected number of flies that are tan but have normal wings

Answer:

WILD TYPE= 425;

TAN-BARE= 425;

TAN= 75;

BARE= 75

Explanation:

Fifteen map units apart implies that 15% of the offspring are products of recombination.

Out of 1000 offsprings, therefore 15% of 1000= 0.15 × 1000=150

150 offsprings are products of recombination.

100-15 =85%

Therefore, 85% of the offspring are parental.

So, if tan-bodied, ware-winged female was mated with wild-type male resulting in F1 phenotypically wild-type females were mated to tan-bodied, bare-winged males.

The expected number of offsprings that are tanned but have normal wings would be:

Wild type= 50% of 850

0.50 × 850 = 425

Tan-bare= 50% of 850

0.50 × 850 = 425

tan= 50% of 150

0.50×150= 75

Bare= 50% of 150

0.50×150=75

What role does mutation play in the evolution of a species and the development of new characteristics?
aivan3 [116]

Answer:

Mutation plays a vital part in evolution; it is the greatest source of genetic variation. In evolution, it creates a new DNA sequence for a particular gene, creating a new allele. Additionally, recombination can produce a DNA sequence (a new allele) for a specific gene through intragenic recombination.

State 2 features each which viruses have in common with living things
BabaBlast [244]
1. Like living things, viruses have genetic material and 2. viruses can evolve.


- Viruses share many genes with their host cells. Viruses are dependent on living organisms, which lead to some living characteristics - they can reproduce/replicate in living host cells, mutate, appear in different strains, and have unique genetic material. However, viruses are classified as not living things because they can’t carry out the necessary processes that meet all requirements for the classification of a living thing. They do NOT undergo respiration and cannot generate energy needed to survive on its own, but viruses *do* share a few features with living things.

N a pond, tadpoles eat algae and fish eat the tadpoles. around the pond, grasshoppers eat grass and, at night, are preyed upon b
Dima020 [189]
I believe that in this community the tadpoles are: the primary consumers. A n ecological community is the set of all populations of all species found in a given place. Primary consumers are mainly herbivores which feed on plants; which are the primary producers of all the energy in an ecosystem. In this case the tadpoles eat algae (primary producer) thus they are primary consumer.
