Answer:
The female (XcX) is carrier for color blindness while the male (XY) is normal. The carrier female transmits its one X chromosome with gene for color blindness to one of her sons making him color blind.
Explanation:
Color blindness is X linked recessive disorder and followed the criss-cross inheritance wherein the color blind sons get the gene from their carrier/affected mother while the color blind father would transmit the gene to his daughters along with X chromosome.
Since both the parents are normal, the mother (XcX) should be carrier for the disease to get the color blind son. A cross between carrier mother (XcX) and normal father (XY) would make 50% of their sons color blind.
It always starts with evaporation, because without water vapor (the byproduct of evaporation), there would be no clouds (they are made out of water vapor and some other particles). Henceforth, there will be no rain.
The food chains, and food webs that cats are involved in both directly and indirectly will be affected by this situation.
The correct answer is: Inserting a gene into a pea plant to make them resistant to insects
Answer:
Incomplete Dominance
Explanation:
Incomplete dominance is a phenomenon in which the alleles of two genes are not completely dominant over each other and so when they are present at the same time in an organism (heterozygous for that gene) the organism will have an intermediate phenotype that is a combination of both phenotypes.
For example: The flower color in Snapdragon can have three different genotypes as well as phenotypes. The flowers can be red, pink or white depending on their genotype. The allele for red flower (R) is incompletely dominant over allele of white flower (r). A plant with genotype RR will be red flowered and that with rr will be white flowered. However, if a plant has genotype Rr (intermediate), then the flowers will be white in which no allele was dominant over the other and both showed their effect giving a combination of two colors as Pink flowers.
Same is the case with the mating between white and black hen, where offspring was grey in color. This grey was a combination phenotype of two phenotypes.
Hope it helps!
