A substrate enters the active site of the enzyme. The enzyme and thee substrate bind to form the enzyme and substrate complex. And then that is where the chemical reaction occurs. And the after that, that is where the new substances called products are being formed during the process.

For this week's CRQ, you are to design your own genetic cross between a female and a male. Be sure to include each of the follow

svp [43]

Answer and Explanation:

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding. Established parent genotypes and phenotypes are used and are usually compatible with Mendelian ratios and inheritance. The phnomenon influencing this behaviour is the

Law of Segregation,
Law of Independent assortment
and Dominance

For this cross...

Assuming Widow's peak= dominant

1. What are the dominant and recessive traits in cross?

Parent generation or P generation:

gametes: Ww → Widow's peak dominant (W), No Widow's peak recessive (w)

2. Is the male homozygous dominant, homozygous recessive, or heterozygous?

Heterozygousity describes the allelic makeup; these traits are made of two different forms of the same gene.

Male: Ww → with the W.peak;

(Thus, with both W and w this is a heterozygous trait)

3. Is the female homozygous dominant, homozygous recessive, or heterozygous?

However, homozygous traits are made up of the same forms of the gene called alleles.

Female: ww → without the W.peak

(Thus, with both w ad w this is a homozygous trait)

1. genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: Ww× ww

Widow's peak ×No Widow's peak

F1 generation:

genotype: Ww × ww ...(from punnet square)
phenotype: 2 with the W.peak; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with the W.peak; 2 without

Semmy [17]

Answer:

so here correct option is A. 5

Explanation:

solution

as number of population groups live in a definite area is called diversity

so here in 1 there is only 2 groups of population

and in 2 there is 3 types of population groups

and in 3 there is 2 type of population groups

and in 4 there is 4 type population group

but they are not not evenly abundant and population of 1 group that is much less

so it might be a foreign population group

so here in 5 there is 4 type of population group which means it has higher diversity compare to other

so here correct option is A. 5
