A black rooster mates with a white hen. Based on their genotypes, the chance that the offspring will be checkered is 100 percent

The rooster and the hen must be homozygous dominant for their phenotypes, in order for their chicks to display both phenotypes. 

Rooster= BB (Homozygous dominant for black color) 
Hen= WW (Homozygous dominant for white color)

Answer:

Rooster's genotype is  BB

hen's genotype is bb

Explanation:

Let the allele for black color be "B"

and the allele for white color be "b"

let us assume that B is dominant over b

Thus,

Genotype of black rooster mate can be either BB or Bb

Genotype of white hen would be "bb" as b is a recessive allele.

Now it is given that all the offspring produced are checkered

This can happen only when BB is crossed with Bb, so that all the offspring are checkered with genotype "Bb"

So ,

Rooster's genotype is  BB

hen's genotype is bb

Compared the Mendelian Dominance, how to incomplete dominance and codominance increase the number of phenotypes? Provide an exam
REY [17]

Answer/Explanation:

<h3>Incomplete dominance</h3>

In incomplete dominance, one allele is not entirely dominant over the other, so heterozygotes (organisms with two different alleles for the gene) show an intermediate or blended phenotype.

For example, consider flower colour.

  • If the allele for red flowers (R) was dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, and rr) and two possible phenotypes. (Red (RR and Rr) and white (rr)).
  • However, if the allele for red flowers (R) was incompletely dominant over the allele for white flowers (r), then there are three possible genotypes (RR, Rr, rr), and three possible phenotypes (red (RR), white (rr), and pink (Rr))
<h3>Co-dominance</h3>

In incomplete dominance, two alleles are both expressed, one is not dominant over the other. Therefore, heterozygotes (organisms with two different alleles for the gene) express both traits.

For example, consider flower patterns.

  • If the allele for spots (F) was dominant over the allele for stripes (f), then there are three possible genotypes (FF, Ff, and ff) and two possible phenotypes. (Spots (Ff and ff) and stripes (ff)).
  • However, if the allele for spots (F) was co-dominant to the allele for stripes (f), then there are three possible genotypes (FF, Ff, ff), and three possible phenotypes (spots (FF), stripes (ff), and spots and stripes (Ff))

Which below are specialized for life in a hypotonic environment?
OLga [1]

Plant cells are specialized for life in a hypotonic environment.

Answer: Option A

<u>Explanation:</u>

A cell which lacks the cell wall, will expand and burst. At the point when set in a hypertonic solution, a cell without a cell wall will lose water to the surrounding, wilt and presumably die.

In a hypertonic arrangement, a cell with a cell divider will lose water as well. The plasma layer pulls from the cell wall as it withers, a procedure called plasmolysis. Thus it can be inferred that plant cell are specialized for life in a hypotonic environment.
