23. how many dominant alleles does an individual need in order to have the autosomal dominant trait?
24. is it possible to know the genotypes of the three children it-generation 11! ?
should their shapes be shaded?

23. 1

24. Yes, and yes their shapes should be shaded.

Explanation:

23. In order to display a dominant trait, an individual only needs to have one copy of the dominant allele. This is in contrast to a recessive trait, where 2 copies of the allele are required in order to display the phenotype associated with the trait. The dominant allele will mask the display of the recessive allele

24. We are told the genotypes of the parents, which are both homozygous (hh and HH). This means that each child must inherit the h allele from their mother, as that is all she has to give, and the H from their father, as that is all he has to give.

That means all the children will have heterozygous Hh genotype. Because the widow's peak trait is dominant, that means they will have a widow's peak, and all 3 should be shaded.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.
