Answer:
The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1 and phenotype proportion 3:1
Explanation:
The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.
For the characteristic "seed color" the green color would be G and yellow represented as g.
At the cross of two heterozygous squashs:
- Parents: Gg X Gg
- <u>Punnett's Square</u>:
Alleles G g
G GG Gg
g Gg gg
Offspring:
- A pumpkin of green seeds GG (25%)
- Two pumpkins of green heterozygous seeds Gg (50%)
- One pumpkin of yellow seeds gg (25%)
Genotype proportion 1:2:1
Phenotype proportion 3:1
Most of the infrared radiation to the Earth is absorbed and transmitted towards the Earth's surface.
Answer: B
Explanation: the sun is made of gas, which doesn't all spin together at the same speed like a solid rock would.
Answer:
the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin
Explanation:
The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
The kind of cross that the figure describes is a dihybrid cross.
There are different types of cross. In this case, we have a dihybrid one.
<h3>What is a dihybrid cross?</h3>
A dihybrid cross happens between two individuals, animals, or plants with two different pairs of genes.
In this case, the two sets of genes that crossed are:
<h3>Parent 1 gene pairs</h3>
- The h0m0zygous dominant RR
- The h0m0zygous dominant YY
The result is RY.
<h3 /><h3>Parent 2 gene pairs</h3>The h0mzygous recessive rr
- The h0mzygous recessive yy
The result is ry.
As a result, the cross is a dihybrid one because RY and ry, which are two heterozygous pairs that code for different traits, crossed.
RY x ry
