Answer:
the light-dependent reactions and the Calvin cycle
Explanation:
Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle
Answer: study the scientist data
Explanation:
Phenotype is the physical appearance of the organism, which is depicted by the genes. The genetic makeup of the organism is termed as genotype. Both genotype and phenotype are inter-dependent on each other. If the genotype changes, phenotype will change accordingly.
Gene is present in various forms and these forms are termed as alleles. Alleles are classified as dominant and recessive. When the phenotype of the organism is translated into the genotype, alleles are used.
Here, genotype of the tall plant could be either TT or Tt.
<u>Genotype of short plant will be tt </u>only. This is because short height is a recessive trait. It will be visible only when it is present in homozygous state, as in “tt”.
Answer:
1. Polygenic
2. RW
Explanation:
1. A polygenic trait is regulated by more than one gene. The phenotype of the organism is regulated by sum total of all the dominant alleles of these genes. Therefore, these traits exhibit continuous variations and are called quantitative traits. Skin color in humans is an example as it is regulated by more than one genes and the phenotype is determined by total dominant alleles of these genes.
2. If allele R gives red phenotype and the W gives white phenotype, a cross between RR (red) and WW (white) would produce all the cows with RW genotype. The parent cow with RR genotype would form all the gametes with R allele while all the gametes from WW parent would have one copy of the W allele. The random fusion of gametes with R and W alleles would produce progeny with RW genotype.
Explanation: This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an individual receive both allele of a heterozygous gene, and have equal phenotypic expression
An example is the AB blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.
Incomplete dominance refers to a blend of alleles where one does not have full dominance over another another, therefore gives a new phenotypic expression different from both alleles.
