Answer:
there is usually no difference. The offspring is genetically identical to the parent.
Answer:
Miscigenation between ethnicities
Explanation:
Sickle-cell anemia is caused by disturbances in hemoglobin, one of the blood components. This disease can lead to kidney, liver, heart and bone complications.
Sickle cell anemia is a genetic disease originating in Africa, so white Americans usually do not have the sickle-shaped hemoglobin (Hemoglobin "S") gene.
Due to the miscegenation between West African blacks and American whites, the probability of having the allele gene for sickle cell anemia is <u>reduced but not canceled</u>.
Interestingly, the countries with the highest incidence of sickle cell anemia are the countries where there are endemic cases of malaria, a disease that directly attacks hemoglobin in blood, but cannot settle in the "S" hemoglobin characteristic of sickle cell anemia.
Answer:
4)
Explanation:
Gametes have one haploid (n) genome, which is half of somatic cells, having one diploid (2n) genome combined through fertilization from two haploid (n) gametes.
In humans, gametes have 23 chromosomes, and somatic cells have 23 homologous pairs, which is 46 chromosomes.
Different species have different numbers, but most follow the same pattern.
What type of connective tissue continues to grow as we age?
Answer:
Lipofuscin
Explanation:
As aging continues, waste products build up in tissue. A fatty brown pigment called lipofuscin collects in many tissues, as do other fatty substances. Connective tissue changes, becoming more stiff. This makes the organs, blood vessels, and airways more rigid
