A trait I which the alleles are not dominant over one another
JulsSmile [24]

Answer:

They are co-dominance and incomplete dominance.

<h2 />

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.

Describe the actual and relative sizes of a virus, a bacterium, and a plant or animal cell.
anzhelika [568]

Answer :

The animals are categorized into 2 groups - eukaryotes and prokaryotes. The microbes like bacteria are coming under prokaryotes. They are unicellular organisms and without a true nucleus.

Viruses are the connecting link between the living and non - living. They are smaller than bacteria. The microbes less than 100 micrometer can't be seen by the naked eye. They can only visible under a microscope.

Viruses like polio, flu virus sizes are 10nm. But some of the viruses are also less than 10nm. The size of bacteria is 1 micrometer. The viruses are 10 times smaller than the bacteria.

The eukaryotic organisms are more advanced and multicellular. Their cell size is larger than bacteria and viruses. The red blood cells under the light microscope are 8 micrometers. The typical animal cells like sperm are 60 micrometers and a skin cell is 30 micrometers. The plant cell for example pollen is 90 micrometers.

The eukaryotic cells sizes are more than prokaryotes like bacteria.

7. What kind of cross does this figure describe?
Kipish [7]

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
