In humans, not having freckles (f) is dominant to having freckles (f). not having a cleft chin (c) is also dominant to having a cleft chin (c). which statement is true of the offspring of a cross between parents that are both heterozygous for both traits (ffcc)?

Punnet Square
 
        F       f
              
C     FC      Cf

c       Fc      cf

25% is homozygous recessive for having a cleft chin and freckles
25% is homozygous dominant for not having a cleft chin or freckles
25% is heterozygous dominant for having freckles and not having a cleft chin
25% is heterozygous dominant for having a cleft chin and for not having freckles

Hope this helps!

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

Reactants are mean lol
