Oxygen-Evolving Organisms Have two Photosystems that Operate in Series, explain by emerson that is the Photosystem I preferentially absorbs far-red light of wavelengths greater than 680 nm; photosystem II preferentially absorbs red light of 680 nm and is driven very poorly by far-red light; Another difference between the photosystems is that,

a.) Photosystem I produces a strong reductant, capable of reducing NADP+, and a weak oxidant

b.) Photosystem I produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem II

c.) Photosystem II produces a strong reductant, capable of reducing NADP+, and a weak oxidant

d.) Photosystem II produces a very strong oxidant, capable of oxidizing water, and a weaker reductant than the one produced by photosystem I

Genes that control coat color in mammals represent some of the best early examples of genes with multiple alleles exhibiting different phenotypes. A classic example is the C gene in hamsters. Three of the known alleles of this gene are C, c^a and c^k. Each supplies a different amount of black pigment to the coat hair. The phenotypes of three different homozygous strains are as follows.

would mate the true-breeding c^a c^a hamsters to the true-breeding c^k c^k hamsters to produce heterozygous c^aand c^k F1 progeny, the F1 progeny cack hamsters self fertilized, From the fraction of F2 progeny that have the wild type black phenotype,

Crosses and their interpretation that would have allowed geneticists to come to the conclusion that ca and ck were likely to be alleles of the different gene.

What will be the ratio of F2 hamster;

In the following pedigree shows the segregation of two different recessive traits.

Assuming that both traits are due to linked autosomal genes that are 10 cM apart, calculate the probability that the indicated child will have both recessive traits.

In the following pedigree shows the segregation of two different recessive traits.

Derive a general equation relating the probability that the child will have both traits expressed as a function of the distance between the markers in cM.
