Answer:
<h2>Both Yy</h2>
Explanation:
1. As  given here, 
Total offspring are= 124;
that produce yellow squash= 93;
that  produce green squash= 31;
2. Let Y  for yellow producing squash and y for green squash;
Y is dominant over y.
3. Cross between two yellow squash producing plants 
Genotype of parents = Yy and Yy
offspring = YY, Yy, Yy and yy,
as Y is dominant over y, so YY and Yy all produce yellow squash, and yy  produce green squash.
4. Their phenotypic ratio is 3:1 , as in question 93: 31
 
        
                    
             
        
        
        
The answer is asexual reproduction. This type of reproduction does not involve fusion of gametes. The offspring arise from a single organism and inherit the genes of that parent only. Consequently, there is little variation from parent compared to sexual reproduction.
 
        
                    
             
        
        
        
Neutrons
The atomic mass is the weight of the protons and neutrons in the nucleus.
        
                    
             
        
        
        
Lethal alleles cause the death of an organism prenatal or after the birth. Lethal alleles are usually a consequence of a mutation and they can be recessive, dominant or conditional. Since the lethal dominant alleles are harmful whether they are carried in homozygous (e.g.AA) or heterozygous (e.g.Aa) form,  a strong selection against them is present and thus these alleles are much more rare.
 
        
             
        
        
        
Answer:
The insect species being studied has three pairs of homologous chromosomes. The first two pairs are autosomes; the last pair are sex chromosomes. Sex determination is the same as in humans (XX=female, XY=male).
