Fruit flies have eight pairs of chromosomes. Calculate the genetic possibilities from independent assortment of a zygote made fr

Furkat [3]

Answer:

256

Explanation:

If there are 2 pairs of chromosomes Aa and Bb, there are 4 possibilities for independent assortment of gametes:

A w B, aith with b, A with b and a with B.

If there are 3 pairs of chromosomes Aa, Bb and Cc, there are 8 possibilities:

ABC, abc, ABc, Abc, aBC, aBc, abC, AbC

This corresponds to 2^n, where n= the number of chromosomes.

Therefore, with 8 chromosomes, the possibilities are 2^8 = 256

This is for each parent.

Butoxors [25]

Answer:

The correct answer would be - predective ecology for ecological model evaluation.

Explanation:

Predective ecology involves the knowledge and data to predict the environmental issues and patterns in future. This method involves the knolwedge of ecology, physiology and physics to ccurately predict the changes will be seen in cosystem or ecology and its biotic and abiotic factor.

Model evaluation is also a method that alow ability to use the known data and model developed on this basis to predicts problems and patterns.

In humans, the trait for tongue rolling is dominant over the trait for the inability of a human to roll his/her tongue. If a het

MrMuchimi

50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.

Explanation:

Information given:

the ability to roll tongue is dominant, the genotype would be RR, Rr

the inability to roll tongue is recessive trait the genotype = rr

Given that heterozygous male is crossed with homozygous recessive female, the genotype is

Rr X rr

Punnet square shows that:

R r

r Rr rr

r Rr rr The genotype ratio is 1:1

phenotype ratio is 1:1

There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.

Which of the following information could be included in the description of a grasshopper’s niche, but not in a description of it

Ivan

The niche of grasshopper would include the plant species it eats.

Explanation:

The niche of an organism is different to that of a habitat. A niche includes the interaction between organisms and the food that they eat, whereas, a habitat is a place where organisms are provided with food, protection and shelter.

Habitat is a place of ecosystem that involves other environmental factors like- rain, sunlight, humidity etc. So, food type eaten by grasshopper would be the description of a niche and not a habitat.
