look up in ur book meiosis which will explain more
Answer:
25%
Explanation:
The female with brown teeth had a father with normal teeth. Since normal teeth is a recessive trait, the father would have been homozygous recessive for the trait and would have transmitted one recessive allele to the female. Therefore, the female is heterozygous dominant for brown teeth.
Let's assume that the allele for brown teeth is X^B while the one for normal teeth is X^b. The genotype of heterozygous dominant female would be X^BX^b and that of the male with normal teeth would be X^bY.
A cross between X^BX^b and X^bY gives progeny in following phenotype ratio= 1/4 daughter with brown teeth: 1/4 daughter with normal teeth: 1/4 son with brown teeth: 1/4 son with normal teeth. Therefore, the probability of having a daughter with brown teeth is = 25%
Energy drinks tend to lack nutrients, and instead contain vitamins, minerals, and stimulants that interact with metabolic pathways to provide energy.
Metabolic pathways- A metabolic route is a series of activities or relationships between genes and associated byproducts that leads to the synthesis or modification of a system component that is necessary for a biological system to function properly.
Genes- The fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes inside the cell nucleus.
DNA- The molecule found inside cells that carries the genetic material necessary for an organism to grow and operate.
