Answer:
<h2>White:120
</h2><h2>Yellow:30
</h2><h2>Green: 10</h2>
Explanation:
Given;
W codes for a dominant white phenotype;
w codes for a colored squash;
the Y codes for a dominant yellow phenotype;
the y codes for a recessive green phenotype.
The phenotypes from the first locus mask the phenotype produced by the second locus.
A dihybrid squash, of Ww Yy, is self crossed
WwYy * WwYy
F1 are:
WWYY,WWYy, WWyy, WwYy, Wwyy,wwYy, Wwyy and wwyy etc
Due to dominant epistasis, the progeny are:
White:120
Yellow:30
Green: 10
Correct option a) (A) One-quarter will carry the two normal chromosomes, 4 and 12, one-quarter will have only the two translocation chromosomes and no normal chromosomes 4 and 12, and half will have one normal and one trans-located chromosome.
Genetic carrier screening , prenatal screening for aneuploidy and prenatal diagnostic testing have expanded dramatically over the past two decades. The presence of chromosome abnormalities in couples with repeated spontaneous abortion is known even if the phenomenon is far from a complete assessment.
If gene on chromosome or on different chromosomes the recombination frequency 50% . Inheritance of alleles at the two loci are independent.One partner is carries of such balanced translocation have increased risks of infertility , and the chromosomal abnormal offspring.
Genetic counselor should answer to their consultants is to estimate the probability of recurrence of unfavorable pregnancy outcomes among their future pregnancies. The occurrence probability for individual carriers of two different autonomy- Autosome translocation with breakpoints at different positions by stengel- Rutkowaski et.

Answer:
A metallic bond of copper atoms with metallic bond of tin atoms to form metallic bond.
Explanation:
Metallic bond is a type of bond that is formed between positively charged atoms in which there is sharing of electrons between them.
Metallic bonds are formed between metal atoms. When metal atoms unite, they share electrons among themselves and each one of them has valence electrons.
Bronze is an alloy of metals and it consist of copper and tin which makes them to be bonded by metallic bond.
Answer:
Codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is dominant over the other allele of the same gene. When present together in a heterozygous genotype, both the alleles are able to express themselves. In the given example, a cross between blue and yellow flowered plants obtained the progeny with blue and yellow speckled flowers. Here, the alleles of blue and yellow flower color are codominant and express themselves in the hybrid progeny.
