      c      c

C   Cc     Cc

c    cc      cc

The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.

there will be 50% chance of the child to have cleft chin.

Answer No 3:

        A        a

A     Aa       Aa

a      Aa        aa

There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.

Answer No 4:

    B      b

b   Bb    bb

b    Bb    bb

As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.

Answer No 5:

           F      f

F          FF    Ff

f           Ff     ff

As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.

Calculate the number of neutrons in an atom of an element that has a mass number of 98 and an atomic number of 42
olya-2409 [2.1K]
There are 56 neutrons. To find them, you just have to subtract the atomic number with the atomic mass. If you dont know, the atomic number is the number of protons (and electrons) in an atom. The atomic mass is the number of both the protons and neutrons. Of you subtract the atomic number, you get protons.
