Answer:

Genotype of long winged fly is Ll

Genotype of short winged fly is ll

Explanation:

Given

Allele for long wing trait is "L"

Allele for short wing trait is "l"

When a long winged fly is crossed with a short winged fly, half of the offspring have long wings and other half have short wings as the ratio is 1:1

Let us say that the genotype of long winged fly is Ll

and the genotype of short winged fly is ll

The cross between the two will produce following offspring

Ll * ll

Ll, Ll, ll, ll

Out of four off spring two have long wings (Ll)

and the other two have short wings (ll)

Thus the ration of long to short wing offspring is 2:2 i.e 1:1

What is not something which can be measured to find the rate of transpiration
olga55 [171]
Correct answer - potometer.

Why? - The potometer does not measure the rate of transpiration accurately because not all of the water that is taken by the plant is used for transpiration (water taken might be used for photosynthesis or by the cells to maintain turgidity). The potometer measures the rate of uptake of water.

Complete the graphic organizer to summarize exceptions to Mendels principles
Butoxors [25]

Answer:

<em>Exceptions to Mendel's principles: </em>

Does exceptions mean that Mendel was "wrong"? The answer is "NO". It means that we know more today about diseases, genes, and heredity than compared to what he expalined 150 years ago. Here I have summerized the exceptions with examples:

<em>Incomplete dominance</em>: When an organism is heterozygous for a trait and both genes are expressed but not completely.

<em>Example</em><em>:</em> SnapDragon Flowers

<em>Codominance</em>: When 2 different alleles are present and both alleles are expressed.

<em>Example</em>: Black Feathers + Whites feathers --> Black and white speckled feathers

<em>Multiple alleles</em>: Three or more alternative forms of a gene (alleles) that can occupy the same locus.

Example: Bloodtype

<em>Polygenic traits</em>: more than one gene controls a particular phenotype

Example: human height, Hair color, weight, and eye, hair and skin color.

Pathogens are transmitted in only two ways: by direct contact and by vectors.
Marina86 [1]

Answer: False

Explanation:

Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.

The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.

The mode of transmission can be vector that carries disease and helps in disease transmission.

So, the pathogens can be transmitted by direct contact, indirect contact or by vectors and by many more ways.
