-23 in males

In humans, 23 in males is the only homologous chromosome pair that isn't the same.

Explanation;

-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.

Blue Genotype BB Yellow Genotype YY What would be the Genotype for Blue and Yellow? A. BY, or YB B. GG C. Not Possible D. BuYe
Fittoniya [83]

Answer:

A. BY, or YB

Explanation:

This question is depicting a phenomenon in inheritance called CODOMINANCE, which is a type of non-mendelian inheritance in which two alleles of a gene both express themselves in that gene. In this question, the allele for blue color (B) is codominant with the allele for yellow color (Y).

This means that an individual that has a blue phenotype will possess the genotype BB while an individual that has a yellow phenotype will possess the genotype YY. Hence, in an heterozygous state in which both alleles combine to produce a simultaneous blue and yellow phenotype, the genotype will be BY or YB.

What assumptions did Engelmann make in order to conclude that red and violet-blue light were more effective than green light in
iren [92.7K]

Answer:

The distribution of chloroplasts in each algae cell was approximately the same.

The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.

Explanation:

Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.

The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
