Answer:
Option B, He has a homozygous genotype
Explanation:
A dominant allele is one which will overshadow the expression of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed. Therefore , if a recessive allele trait is to be expressed , the offspring must have both the recessive allele
Let us see case here
A. Allele for attached earlobes is recessive (e)
B. Allele for detached earlobes is dominant (E)
If offspring has EE genotype, then he/she would have detached earlobes
If offspring has Ee genotype, then also he/she would have detached earlobes as in heterogyzous genotype traits of dominant alleles are expressed.
If offspring has ee genotype, then only he/she would have attached earlobes
Genotype ee is a homozygous recessive genotype
They can learn from other scientists mistakes and build off successes or failures.
Answer:
The answer is D!
Explanation:
"Genes are regions of DNA that carry the code for making proteins."
Cytoplasmic uses actin and myosin for the movement of the cytosol which causes the organelles to move inside the cell.
When fish are caught faster than they can reproduce, the population will slowly dwindle down. Overhunting leads to a decline in the population of the fish until there are ultimately no more fish left to repopulate.
