Answer:
2 children will have freckles
Explanation:
This question is just a play on words for the punnet square. You have a dominate trait , freckles, and a recessive trait, no freckles. Charlie has no genes for freckles, so he will be represented as 2 lower case letters. Stacey has both types of genes for freckles and no freckles, so she will be represented as 1 capital letter and 1 lowercase letter. I'll try to make a punnet square down below. Capital A represents the dominate trait and lowercase a represents the recessive trait.
A a
a Aa aa
a Aa aa
As you can see, 2 of her children have the dominate trait for freckles, and two of her children only have recessive traits, which means no freckles:)
Answer:the radiation of the Sun’s electromagnetic waves
Explanation:
Answer:
The correct option is B
Explanation:
The alpha and beta-gamma subunits both can bind to target proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
Answer:Recessive traits
Explanation: Albinism is a reccessive traits whose effect have been suppressed by the dominant traits in the parents phenotype.
Complete dominance occurs when an allele A completely dominate over allele a in the genotype of an organism.
For the parents to have given birth to a non albino it means they are heterozgous dominant(Aa) and a cross between two heterozygous dominant parents will result in one homozgous non albino,2 heterozygous non-albino and 1 homozygous albino with the phenotypic ratio of 1AA 2Aa,1aa
