Answer:

If the "b" allele denotes color blindness, a color blind woman would have the "bb" genotype.

Explanation:

Although color blindness is a genetic condition linked to the X chromosome, it is very rare for color blind women to exist, although they may carry the allele that denotes color blindness.

This is because women have two X chromosomes, if a woman receives an X chromosome from her father containing the "b" allele (which represents color blindness), but receives an X chromosome from her mother which contains the "B" allele (which does not represent color blindness), this woman will not be color blind, although she may pass the defective gene on to her children.

With this, we can affirm that, in women, color blindness is only expressed in recessive homozygosity, for this reason, a color blind woman would have the "bb" genotype.

Why were members of the upper class in Maya society
ziro4ka [17]

The king held the highest position in society and priests, warriors, and merchants were also part of the upper class. The Maya believed their rulers were related to gods. Rulers were involved in religious ceremonies, led battles, had beautiful clothing/jewelry, and Kings wore huge feather headdresses and capes of cotton, jaguar skins, and feathers. Priests led religious ceremonies and were the most educated. Warriors fought battles with animal headdresses, jade jewels, and jaguar skin capes on their red and black painted bodies. Merchants directed trade among the cities and organized the transportation and distribution of goods. Together the members of the upper class controlled the politics, religion, and ceremony.
